I've heard lots of good things about the Yazbeck and the reports of the Riffe are good also. Everybody has a favorite suit. You'll see people on SB say that their Spetton is the best, or their Apnea, and so on. The big thing is to get good rubber and good stiching and most of the suits are getting better and better. If you don't fit into off-the-rack suits very well, then that's the time to look at custom. My Elios fits like a glove. They actually emailed me and told me to re-measure because they thought a couple measurements were off a little, and they were right.
Hey man, my fellow Wilmingtonian Ren Chapman tells me that you are the man to ask. I'm in the market for a new suit. I'm 5'11" and 170lbs, I have wide shoulders and a narrow waste. There are many options for 5 mill suits. So far it seems I've narrowed the list down to Riffe and Yazbeck. Though, I would like to know more about your custom Ellios suit.
