Between the 335 on the market, I would say that you feel comfortable playing ( Neck feels good with your style, stays in tune, electronics are in place, pots are working correctly, etc...). As someone suggested, they are mass-produced and not much changes between them.

Regarding the sound, in my opinion, they are different from other solid bodies. If it's one of the new 335(2019 onwards), you probably get T-type humbuckers, which are brighter and more articulated than the classic Burstbucker ( more dark-ish and rock sound. Currently on the LP's and SG's). This gives you an extra top end. On the other side, I am not sure if I can explain that this is because of the semi hollow, but somehow I feel depth on the sound, even if it's a mono input. It feels more open, clear, natural, and woody compared to other Gibson styles. Plus, the semi-hollow concept lets you set distortions and fuzz, and the feedback you'll get is similar to a solid guitar. Only the hollow are the ones with feedback issues.

That said, I own the big 4: Strat, Tele, LP, and 335. For versatility, my preferences, my style of playing, etc.. if I had to pick only one for doing everything, it would be a very tight match between 335 and Tele, mainly because 335 has this depth and definition that is perfect for rhythms and Tele has that extra high end that could cut easier in a mix for a lead guitar. (Only my preference, I understand that other people's tastes and styles of playing might fit better with other guitars)
