I play a Gibson J45 as my main axe.  I've tried all kinds of strings and in general do not like the coated versions that have become popular.  The Gibson came with a set of Gibson strings on it naturally, but I still tried a bunch of others.  I play every day, but ALWAYS put a new set of strings on when I play a gig, and if doing several gigs in a short period of time may only let one set go for two outings.  So, I am willing to spend money to get the sound I want.  However, I want them to deliver too and these strings just do.  They have that right blend of bottom end and punch I want.  The J45 is a rosewood version and it begs for that full sound that these strings can deliver.  They feel good, they last (if I put a set on and don't gig for a couple of weeks they hold up to daily use), and they have a good balance of tension and playability.  So, for this guitar and another similar style guitar these are my strings of choice.
