Not a mean question at all. I haven't had more difficulty keeping a working system than I did on Debian, Ubuntu, Mint, Fedora, etc. I get everything I need in Arch and the packages are always fresh off the grill. I also like the emphasis on text config files and a ground-up install. That helped me better understand my system and how it works.

No idea about performance. My performance recommendation is "don't run Windows!" :)
