i like osx but im a mac nut.
suse has many key commands similar to windows so its a good transition but its no slouch under its belt and can perform quite well as a linux distro.
redhat or fedora is a good stable linux distro thats earnt its place and grown to be a good solid version of the distros around.

is a good site for all the different flavours.
