You have to try a few and decide for yourself which one suits you the best.
That is why Linux will likely never be much more than a geek plaything. Most average users don't want to spend time doing trial and error for dozens of distros/desktops.
A few years ago I saw a listing of around 100 distros.
I do have a Linux Mint laptop that I use occasionally, but I still revert to Win7 to do real applications work. I did spend hours going through old Linux books. Mostly, it reminded me of the early days of MS-DOS, as too much still has to take place via terminal.
Even at the rate MS is trying to kill Windows, Linux will have a tough time trying to gain a viable foothold in the world of the average user.
The 100 distributions pose another problem: Commercial software vendors are not going to support 100 distributions for their product.
As I’ve said elsewhere on this forum: Desktop Linux is a failure.
