@Cixoea :-
Simply wanting "different looks" is not really a good enough reason in itself to make the switch. After all, theming is, to a greater or lesser degree, available across all platforms.
However; THIS might pique your interest. It's a video demo - from a guy called Philip J. Bugsington - of the "full Monty", utilising a KDE desktop, Compiz Fusion, the Cairo 'dock', "wobbly windows", the legendary 'desktop cube'.....
the "works".
Linux was capable of doing ALL this almost 20 years ago.....long before Redmond even
thought about multiple workspaces..! (Okay, the back-room boys'n'girls
did develop a "PowerToys" multi-desktop pager widget for XP, but that's all it ever was.....and it didn't work very well).
Looks-wise, Linux has been able to leave M$ in the dust for decades. Many of the effects shown above are no longer available (I don't think it's been actively developed for years; most references on the Compiz site seem to date to around 2009). About the only currently-available distro I know of that even has SOME of them, OOTB, is
Knoppix......the original 'run-from-a-flashdrive-with-persistence' Linux OS. And much of
that seems to be some years out-of-date.
