It would depend on your collection I suppose. They all have appeal depending on what function and aesthetic you’re looking for.
I’ve been able to but all three but chose the GMT. I find it to be a useful complication compared to the Chronograph for which I have little use for. I was seriously considering the SkyDweller, but I found the dial a bit difficult to read, and I wasn’t certain I’d like the annual calendar ... sometimes less is more I guess YMMV
