I had a thermaxx 3 mil that I loved and kept me warmer than my previous 3 mil wetsuits. Our students use the thermaxx 7 mils for check out dives in NE and if they get the right fit, the inside is almost dry when they take it off, there is not a lot of water exchange happening. I have worn a 7 mil thermaxx, with a thermaxx 3 mil vest, and been far warmer than in my previous 7 mil and vest. So my experience is that not only are they as warm as suits of comparable thickness, but actually warmer. All of the divers I know here in NE who have used them (which is quite a few) are of the same opinion.
