git or mercurial (not flamebait)

Hi,

So, I am new to both git and mercurial (but not SCM) and would like to try one out.

After reading about each for a few hours I can't really decide which one to invest some effort into. So, I decided to decide on which one to use by which one has better IDEA support.  I was hoping there might be a clear answer to that, but if not, maybe I'll flip a coin, or see if I can which one might work better under Mac OS X.

In any case, I'd welcome some thoughts on this question or more pointers to objective articles that compare the two.

Thanks in advance,

Spencer
