I use Mint 7 Gnome x64 because of many reasons.
Mostly because it is rock solid stable and it runs on even the most modern hardware as well as very old hardware equally as well.
The only wish I had was for better WiFi support.
I like Grub 1 , no uuid , Gnome 2 , the fact this it is surprisingly light on system resorces , etc... etc... etc...
Basically it is just exactly as I want , and I know how to do just about anything I need to do with it.
I NEVER do any online banking or personal transactions etc. so I have no worries about Security.
If anything happens , I can just reinstall in about an hour and am ready to go again.
( I do think Mint 9 is a better choice for most laptops because of better hardware support. )
Have tried out every version since Mint 5 , also KDE & XFCE & LMDE variants hoping something better would come along.
But so far nothing has... I kind of think Linux and Gnome in general is going in the wrong direction for my tastes.
Everything is becoming more bloated , complicated , less stable and less configurable. I know most people want
to stay on the "Cutting Edge" of technology , but I guess I am happy just sticking to what I know and like.
But hey , what do I know ? I still use Windows 98se and still play Wolfenstein and Doom II once in a while
