Interesting that you started this topic... I was going to start the same topic a few weeks ago but got distracted with more research.
Anyway, I too am looking for an awesome red habanero type to grow next year. I had initiated a seed trade several months ago for some Antillais Caribbean Reds, but the seeds never arrived and the member has been absent here since with no reply to pm (hope they are OK).
I grew Caribbean Red habs a few years ago and they are pretty good.
Last year I grew PI 585278 (Galapagos Island Large Red Habanero) and thought they were fantastic. Great flavor, thick walled, juicy, but very mild heat for a habanero. And that was my only complaint, I wish they were hotter.
I also grew the MOA Red last year. To date that is my favorite red pepper in the habanero range of heat. Hotter than the yellow MOA, fantastic flavor, thick walled, nice sweet fruity flavor. It is a scotch bonnet though and has a different flavor profile than the habanero.
Recently I tried the Mayan Red Habanero that was included in a seed saver box I purchased. I liked this pepper very much and it may be the one I decide to grow next year. Heat wise it was about orange hab level, not as hot as the MOA Red, but had a great habanero chinense flavor. It was not as thick walled as the MOA red, but had a medium thick flesh that was nice and crunchy.
Another one on the list could be the West Indies Red Habanero. I have seeds from this variety from last year but I elected to grow the CARDI Moruga habanero instead this year. I'm still hoping to see ripe pods from this by the end of the season.
Scotch Bonnet Safi also seems like it would be a good choice. I had considered getting seeds for this one at some point.
I agree with the comments about the chocolate hab... it is one of my favorite chocolate peppers. I have also read great things about the Jamaican Hot Chocolate and would like to try that one at some point.
I would be happy to send some seeds your way at the end of the season if you are interested in any of the ones I have.
