The way a guitar plays is influenced by action, truss rod, pickup settings, etc.

Dozens if not hundreds of variables, of which strings are only one small part.

I can tell when strings are new or worn, but frankly in 12 years I've never said "Oh these strings make my guitar play bad".

Action and so on being looked at by a tech is where I'd go if I had that problem. Its also likely your guitar needs a fret level if you've played it for a long time without a tech seeing it. A lot of guitars need tech attention from new, even.
