I have both the Crye combat and Arc Talos, and like both. I prefer the external kneepads on the Crye to the having to run the dead bird kneecaps through the talos, however both work just fine for protection and are equally comfortable.
For a range or overt stuff, the Crye are my go to, whereas the talos is my preffered for "lower" vis or outdoorsy stuff.
Talos do not fit slim in the thigh, they fit roomy. its a comfortable cut.
I have the vertx phantom LT and tru spec 24/7 pants, and like each about equally. I prefer the design of the cargo pockets on the Vertx, however they have a slim waist (a 34" waist feels more like a 33", however still wearable and comfortable) Both get lots of wear, both trippin around the city and out hiking, camping, low vis/no vis at work, etc.
Button fly isnt a deal breaker for me, I just prefer zipper. Faster, easier, etc.
Combat shirts i have an arc talos LT (prefer the older model with the higher collar) and a Crye Combat, as well as a couple of the older CP gear cadpat AR OTW shirts. The Talos LT is a nice shirt for romping around the woods no armor or weapon, but im not a fan of the low pro collar, I find stuff (slings, armor carriers, etc) tend to rub and I notice it more than the standard combat shirt collar. This seems to have been corrected by the new "Assault ar" shirt from arcteryx. the Crye combat shirt is G2G.
Vertx, Tru spec, etc all have combat shirts, however I have no experience with them.
in an ideal world with an ideal budget, a pair of each would be where its at.
