TopSub SuperCaccia model has soft Yamamoto neopren. Smoothskin outside and open cell inside. Very comfortable and warm. Ive bought the 7mm jacket of the suit for cold water and am thinking of getting the high-waist trousers as well.
Elios also good choice and probably Marea too but prices for Marea are too high in my opinion.
