You have a similar calculus to me. It's a beautiful watch. But as you say, the Pro functions ostensibly as a field watch with an am/pm indicator. The only party trick the Pro really brings to the table is the jumping hour hand, which is immensely (understatement) satisfying when you're actually traveling.
For me, I want a tool watch to be as flexible a tool as possible. I use my rotating GMT bezels to time things constantly outside of work, just like a diver bezel (which is why all the newer 24 click GMT bezels are suboptimal) by lining it up with the minutes hand. But a 120 click GMT bezel is even better than a dive watch because you can time events up to 24 hours by timing off the 24 hour hand.
And for work I leave the GMT hand set to UTC 0 (or Zulu time) and then use the bezel to quickly adjust whatever 2nd timezone I'm tracking at any given moment based on the +/- offset. This is something you cannot do with the Pro. You're married to tracking one 2nd time zone all the time, unless you want to hack the watch.
Personally I think if you're going to buy a fixed bezel GMT and need to track other time zones often, you're better off with a caller GMT complication which makes this 10x easier.
I have both caller and traveler GMTs, both with rotating bezels. And I struggle to find any rational use case for a fixed bezel + 24 hour GMT hand. I'd be better off with a thinner dive or field watch that looks equally cool/rugged.
And that's ignoring all the practical questions of whether it fits equally well on a hike as it does a work dinner
