If you had to choose

That blue dial is the one to keep! I’d love that myself, but the most I can go for is one of the low end quartz GS And that’s gonna take some saving. 

Ohh man I‘m eyeing this lately for the price!! I was debating to get this or go with the Seiko Persage Shippo enamel …

I‘d go blue. Just as an FYI, I do use my GS bracelets watches as daily wears. They hold up well, but it has to be something you like to do. 

The GMT is very 😐
While the blue is 🤩

Writing the brand initials all over the dial like that comes across as a bit self-indulgent. Not very classy.

In your position I might sell both, and get a smaller dressier piece, for those special occasions. (Selling the SLGA007 would probably hurt.)

I'm going to suggest something absolutely heretical here:  Sell both of them.

• The fact that you're undecided between which of the two to move on from indicates that both are on the cusp
• You're not a luxury watch kinda guy, and both are clearly luxury watches
• Both are highly sought after, but from your own description - "I've got two of my most desired pieces from a brand I've grown to love, however..." - it sounds as though one of the reasons you may be holding on to them is simply because they're so highly desired.  That's no way to live!  I used to date this gal in New York, who was perhaps the most comely female I'd ever / will ever set eyes upon.  Everywhere we went, heads turned.  Yet, I found that I always wanted to tear my own ears off every time she opened her mouth!  So, what others find desirable is not always what we ourselves want in life, yeah?

If you sell both, someone else will certainly immediately move to purchase, they will get to enjoy, and you will have a wad of cash with which to then pursue watches that better fit your preferences.  Win-win!

May I suggest any of the following, which may better suit your "non-luxury-watch-guy" lifestyle...

Amongst the lot above, it would be a tough call between the SBGN005 and the SBGE257.  The former is thinner and sports a comfortable 39mm diameter, and is quartz, so is tougher.  The SBGE257, meanwhile, is thicker, but has spring drive, and that smooth sweeping seconds hand is soooooo satisfying.

In the meantime, sir, my condolences that you must deal with this truly crushing first world problem.

I agree with @HotWatchChick69. Sell both. 

The way you talk about them just comes across as you feeling a bit 'meh' about both. It's like you have lusted after them, realise how special they are to many people, and so just feel kinda compelled to keep one. I'm not really sensing any passion for either. 

You need to find a dress watch you look at like Turmond looks at Brienne.

Chris that GMT is probably my favorite GS that I have never personally seen. The closest I have come is the SBGJ249, so I can understand your chandelier comment, though I was in a very brightly lit WOS. But I went from thinking i "had to have it" to " I don;t think I could live with this" ---- aybe you should think about something more subdued...but perhaps I'd hold onto that GMT a while longer...I'd hate for you to have sellers remorse

Don't disagree with this observation. But there's no down side to moving more slowly, keeping one of the two for now then take a wait and see approach with it. I'm sure your collection will continue to evolve, and you'll continue to learn more about yourself as you go along. No upside to making drastic changes that you'll regret.

To answer your question though, I'd agree with the popular opinion here and go with the suwa for two reasons:

• It's the less dressy of the two. If anything its size makes it a bit more sporty. Most people not in the know probably wouldn't even identify it as a luxury watch. It's just a seiko right?
• The evolution series is such a breath of fresh air in the watch world. While most brands are busy pay tribute to the past and honoring design "traditions", the evolution series feels very forward looking, both in terms of the movement (5 days SD are you kidding me?) technology and case design. It is a bold move to go with a 22mm lug width for example, probably against convention wisedom. But it's a design decision that yields better stability on the wrist. I don't find it unweildy at all since there's still a good amt of taper. GS is taking the lead and saying to the rest of the world, "get on my level".

All very sober-minded and good advice...  except...  OP, do you want to do this all your life...

...  or would you be happier if you grabbed your fate by the reins, sold whatever doesn't really excite you, and go out and discover the watch you really love, and say to it...

• If you got both watches at MSRP, you will make a very tidy profit on the sale
• If you didn't get both watches at MSRP, and instead paid market price, you obviously have enough money that it doesn't matter one way or the other whether you make a few dollars here or lose a few dollars there
• Unless you're one of these live fast, die young types, who suffers from hyperbolic discounting, my guess is that you probably work hard, save up money, live responsibly, don't drink or use drugs to excess, max out your 401k, etc., etc.  And, one day, you're going to end up with too damn much money in your retirement account.  And you'll be old, like me, and you'll say to yourself, "Why the hell didn't I just spend a few bucks and enjoy my life?  I can't take this cash with me where I'm going!"

So, obligatory...

I would say KEEP BOTH. And it seems to me that you can afford to keep both. If you really love both watches, why let any of them go? Its not about logically ”I only need one because I am not a dressy kinda guy”. This hobby is not about need, this hobby is more emotion than logic. Why the hell do any of us NEED so many watches in the first place? 🤣
