Personally used netbeans for a while to write ruby + haml
yes, it is a good for ruby, and has haml syntax coloring
but, as long as haml is tab sensitive, netbeans lacks such powerfull feature like Identation Guides
these vertical dotted lines helps a lot
and i found them in Komodo Edit
of course there are an haml plugin for Komodo Edit, but it does not actually works for me
even with no syntax coloring for haml, i switched to KE, cause it is die hard to write haml without Identation Guides
for ruby code i use eclipse
just my 2 cents
