Personally, other than being extremely CPU bottlenecked when going Crossfire, I haven't had any issues other than a couple Capcom games (RE5 and SFIV).
From what I understand though, SLI is signifcantly more optimized than XFire, offering about 90% efficiency versus around 70% with ATI. It's why I tried to sel my 5970 and get two 460's.
SLI will rarely reach 90% even in an artificial test. Even some of the better real world cases (2560x1440 with AA) it's in the 80s, and that's with the 460 SLI which has unleashed some new SLI scaling secret sauce. So not all SLI is quite as efficient, although it is almost always a better scaling solution than XFire and more importantly scales better in more games, especially closer to release.
Of the two multi-card solutions, SLI has proven to be a more generally usable solution for me. Right now I'm enjoying single card gaming with a 5870, but if I was going multi-card, it would be SLI.
