Tempted to switch from Ubuntu Studio to 64Studio

I switched from Windows to LINUX about a year ago through trying an Ubuntu distro and have been an Ubuntu user since. Having tried the original Ubuntu I tried Kubuntu for a while and actually liked it better, it was somehow more responsive. But after the long awaited Ubuntu Studio came out I switched to this flavor. I was not really that impressed and have to admit that this version of Ubuntu does not seem to run as smoothly as I was used to. It did not include the most recent Rosegarden version (it has 1.4.0 instead of 1.5.1), I tried to get LinuxSampler to work and failed (yes I tried to compile, etc, etc). I have also tried Sabayon, Arch, Yoper, Musix, Studio2go, but have so far always returned to Ubuntu. I also have been following the Jacklab distro, but they somehow take their time (I tried a beta 1.0 version and failed...yikes). Although I am a experienced computer user (I write software for a living), my desire is to use Linux for creating music and not spending hours of tweaking and fiddling and trying to get stuff to work (I have been there and done that, so to say). Although I do not really have the desire to switch distros again, I must say that 64studio caught my attention even though I do not have an AMD64 setup. Through Ubuntu I have been getting used to Debian and really started to like this base and having read much positive responses I wanted to check in and say hello and ask some questions. I have been using the fluidsynth as a soundfont player to create ambient/classical (strings/pads/etc) sounding backing tracks to use live in a looping device when I play acoustic guitar. While I am not a 'real' piano player I have been using Rosegarden to sequence MIDI tracks. I wanted to try LinuxSampler too because I expected better results, but had no change yet to try that yet. Also I found the effects that are available not fun work with because of the interface and the lack of presets. I had put my hopes in VST plugins through asio-wine for some time, but while there is a lot of fiddling/compiling involved I have given up a bit on effects in Linux altogether. I did also find no way to make good sounding loops. FruityLoops (Windows) has an simple export function where you can select to wrap-around the tail end of the effects used and voila, a perfect loop, but this still seems difficult to do under Linux as far as I have seen. My brother-in-law if trying to convince to switch to Apple, but I am still hesitant, because I do believe in the concepts of open-source and Linux in general as a better alternative. So the main question is: with the setup below would I gain anything by switching to 64studio instead of UbuntuStudio? And I really would appreciate feedback on the stuff I have written above.
