Interesting thread. I replaced my standard vinyl lines with Bevseal Ultra about two months ago. I could have sworn that I looked into both of these options, and decided that Bevseal Ultra was the better based on what I read here. But now it seems like EVA is the better option. It does sound nice only needing a few feet of tubing, but it's too late to switch at this point.
Overall I'm happy with the quality of the Ultra. My beer tastes noticeably better than it did with the old tubing. There's a little bit of foam/sputtering when I first open the tap, even with a fan in the keezer, but at least it's drinkable once the foam dies down. With the old line, the first few ounces were oxidized so there was just too much waste. I put hooks around the collar of my keezer and I wrap the Ultra line around that, but it's definitely not the easiest line to work with.
With both of these options though, it's strange that most homebrew shops just sell the crappy beer line. It's basically the same price for a significantly better option, but most people don't know about it.
