I use Debian (stable) on an old Netbook of mine. I still like Debian and I don't think it is more difficult to maintain and install then Arch (probably easier to install even, depending on how you see it), but it also means running with older software. For me the reason to use Debian stable was mainly that I don't use the netbook so often and I could not do updates frequently, so the more conservative nature of Debians update policy fits me well for that device.
