While the GUI was nice, it was much harder to set up compared to oprofile so it wasn't all that popular. Things improved slightly when Ingo merged the custom kernel module but the _userspace_ part of sysprof was lagging behind a bit. I don't know what's the situation now that they've switched over to perf syscalls but you probably get my point. It would be nice if the two projects merged but I honestly don't see any fundamental problem with two (or more) co-existing projects. Friendly competition will ultimately benefit the users (think KDE and Gnome here).
