Most people honestly use BrowEdit.
I have yet to have it be 'buggy' for me. You wont find a bug free map editor that I know of.
I suggest using 2 versions, if you decide to, which is 620 and 586.
I also HIGHLY suggest looking at Syouji's BE Tutorials, they're one of the most informative out there and is what I went by when I first started mapping.

Goodluck.
