Truthfully I would get the boat with the best dealer support. There are also plenty of nearly new used boats on the market that I would be picking before a brand new boat.

I've had the pleasure of sailing on 2-3 platforms with a variety of rigging setups. At my level I think all of the boats sailed quite well. There were some rigging setups I preferred for ease of use, but may be less efficient than some of the more complicated setups (for instance, the single spin halyard/ tack line vs. separate, aft-led downhaul controls, "quick set" rotator release)
I would definitely pick one with good (local) dealer support. If I was really concerned with close racing, I'd go with the type most common in my sailing area.
If I wanted lots of pickle dishes, I'd drop a Sheet-load of money and time on training and pick any boat.
