RVM, seriously..?

[frankblizzard]

For the sake of learning rails (railstutorial) I think it doesn't make a difference if you use rbenv or rvm.

Is there a better solution out there? I've found it to be (relatively) painless thus far, though I've been caught out a couple of times.

I like rbenv, it's pretty lightweight.

The only reason to stick with RVM was gem-sets but everybody users bundler these days anyway,.
