As a long time user of TM pistols, they are generally very reliable and accurate out of the box, but there are some that are a little more finicky than others.
Basically, the TM P226 series, Glocks, and 1911 (Including Hi-capa) series hold up quite well all around, as does the Px4. The Five seveN is okay, but the trigger is a little strange on it and very clunky. (I also don't like the ergos of it, but that's not a TM problem.) The XD seems okay so far, but I've noticed that Firefly already released new valves and recoil spring guides to increase the blowback on it, but part of this may be that some of the TM models with heavier slides (like the Px4 and Desert Eagle) sometimes have problems cycling in low temperatures on HFC134/152. On Green gas they don't seem to have any problems.
Speaking of green gas: The M92 series I have heard tend to fracture the slide over time on green gas, but I don't have first hand experience with this. Most of the other TM pistols will run okay on green gas, but I do believe it voids the warranty to do so. At the very least it might be a good idea to put a heavier recoil spring in. I would also be a little wary of the Glock 18C on full auto on green gas. I haven't tried it myself, but it seems like it would be liable to run into some problems.
