What time frame are you looking at? How much work does the pf need? Are you on a budget?
HEP does great work but may not take your playfield.
Ron's work is beautiful but he's booked solid and he may not even do the restoration if he thinks he gets a better result by clearing a reproduction playfield.
I read many good things about Neo.
I wouldn't use TC. I got a crazy quote when I inquired about a clear job.
I got a great clear on a LOTR pf with very minor touch ups from HSA but can't speak about their more advanced restoration work.
