I have that very paddle suit for use with my Ilaga. I use it in combination with the chillcheater thermal layers and it is a great combo.
I’m not a huge fan of the shoulder zip, it’s a pain to get it on and off compared to a waist or front zip. Once it is on it is very flexible though, no issues with mobility or flexing. I liked the fact that it is custom fit for you, so you don’t have to worry about parts fitting and others not.
As for picking one over the other, I wanted a simple solution for self-rescues. I didn’t want to deal with a dry-suit and a tuliq or forgo the dry-suit and worry about taking a swim in cold water. I use a re-enter and roll for my self-rescue so I wasn’t worried about scraping the paddle suit over the back deck for a scramble or anything. However if that was your go-to self-rescue I would be nervous of the paddle suit. The material is tough but I could see it snagging and ripping easier than a dry suit.
I don’t use it in warmer weather though, it’s purely for cold water rolling. I wold use the regular tuliq over the paddle suit if you were primarily using it in the warmer months. Too much of a hassle to put on for anything less than water that is one degree away from freezing.
