Less bubbly? Not likely. But how those bubbles exit varies among the different regulators. If you look at some the reviews in magazines and web sites, you'll notice that bubble interface (or in-your-face...) is one of the things they rate. In my case, I use an Atomic M1 which tends to send the bubbles to the side and out of my field of view. When you get around to purchasing your own equipment, do your homework and try berfore you buy. This stuff ain't cheap...
