I think so. Plus the thumb clusters which makes accessing modifiers like ctrl as well as home/end and page up/down easier than a standard keyboard. I personally never used home/end and page up/down before I got my Advantage 2 but I find I use them more since they are easy to access without going off home row. I also use the "numpad" more and I've taken a lot of common programming symbols like {},[],| off my pinky and onto the numpad layer. Although that's more a pain thing.
I've tried the thumb clusters, and I just mis-hit space too often with them. I'm sure I could get used to them, but I really do prefer a wide space bar with a large target area.
