Re: WLH or PG?
WLH and Pearly Gates are both very good sets with similar output levels.
Difference is in voicing and feel.
Due to the Alnico II magnets, Pearly Gates is saggy in feel, with a sharp top end spike in the bridge. WLH, with its Alnico V magnets, is stiffer in feel (not as stiff as ceramic, though), and more even in EQ.
I personally prefer Pearly Gates for what I do (blues, classic rock, etc.) but would recommend WLH if versatility is important. If I were to play "rock", no adjectives before it, where that could mean anything from Elvis to EVH, WLH would do the job.
