Do you prefer a pin and buckle or deployment clasp on a leather strap?

Either is fine by me but if I'm buying after market I go pin/buckle.

I've yet to experience a deployant clasp on a leather strap, but it mimics a bracelet, so I'd probably like it.

I find the pin and buckle tends to crease the leather a lot more than a deployant.

Deployant makes little sense to me. It puts a big inflexible piece of metal between one's flesh and a perfectly fine piece of leather. Possibly they make sense if one has very bad vision or motor skills, but I'm skeptical. The general argument is the vinyl-slip-covers-on-grandma's-furniture one, that the costly leather is too nice to use normally and so we'll put this obtrusive device there to prolong it since we're not worthy.

I do agree with Ariel Adams on these things. They have become expected on pricier items and get included purely because it seems like the right thing to do. Rather circular reasoning, but people do not always act rationally.

I would say pin and buckle but I have never tried a deployment clasp. I do have a few I am looking at but have not bitten the bullet yet.

To me a deployment clasp is classier is all situations

It depends on what you want from your strap. I hate the bulk of a bracelet clasp under my wrist, so the bulk of a deployant is just as annoying.

I also view straps as consumables, they have a finite lifespan, and shouldn't be expected to last forever. Also, I happen to like the look of a nicely broken strap over the look of a pristine strap that seems like it came out of the box that morning.

As a strap guy, I gravitate most to deployant simply bc it’s quick/easy and more importantly, preserves the strap material 🤙

Deployant clasp every time for me.

I have experience in both. Pin and buckle for me as it is thinner and more comfortable than the deployment clasp. Deployment clasp tends to be either too tight or loose when use on leather straps for my experience and the added thickness doesn’t do it for me.

I have a problem with both! Pin and buckle on many watches fits between my needs and deployment do not work on small wrists :/

I prefer the kind of deployant clasp that Artem Straps refers to as an Omega-style, preferably with on-the-fly micro-adjust, on a strap without keepers. Keepers with this kind of clasp are not necessary, and the micro-adjust makes a much more enjoyable wearing experience when your wrist expands and contracts, and easier to more quickly put on and take off.

That said, I'll take a pin/buckle closure over the double-fold kind where the end of the strap gets tucked into the keepers. This usually makes the strap profile much thicker under the wrist, and makes for a more cumbersome process to close.
