Best choice for Wakesurf boat in $100k range - used or new

I’m new around here and have been recently digesting all the great info on the boards, so I figured I’d throw this topic out there and see what the feedback is.

I’m getting a lake house and will need a boat. Primary interest is wakesurfing. Will never have more than 8 or so people on board. It’s a small lake and boat will be moored at a dock behind the house, so most likely it will be taken out for an hour or two at a time.

I’ve been looking at 2015/2016 Nautique G21 and G23. Thoughts? Am I better off with an older premium boat or a newer “affordable” boat? (Being new to this boat game, all these prices seem somewhat crazy). Is there going to be an appreciable difference in the surfing between the G21 and G23? Should I be looking at Malibu or Mastercrafts from that era? Is there any model that stands out for surfing?

Thanks!
