I have tried most of the major Trisuits, the notable exception being ROKA. Other than that, I would say the new Kiwami Spider 2 Aero is by far the best. As stated, fit is huge, and the Kiwami has an amazing about of stretch, allowing it to fit snug and comfortable on a large range of body shapes. I am small in the waist and hips, but large shoulders, arms, chest and legs- and this is the only suit or even separate piece with absolutely no wrinkles. I did a swim test, Trisuit vs speedo only, and to my surprise I was as fast in the Trisuit as without (I am a 1:20 ish per 100 yard swimmer). This is a good indication that the suit is staying snug, and not creating additional drag in the water, and should perform at least as well in the wind. It has a huge amount of storage, which I was concerned about and don’t need, but the swim test indicated they stay flat against the body and don’t create any drag. I have raced a 1/2 Marathon at 0 degrees centigrade (32 F) and then a 70.3 starting at 1 pm at constant temps at 32-33 c (92 + F) with 75-80% humidity, and the suit was very comfortable for both races, so body heat regulation is very good. The best feature is how well the full zip top is designed. Super easy to get off and pull down quickly, if needed 
Definitely worth a look
