I've used PhoneGap to build an app not so long ago. I had a few early niggles getting it set up but those were mainly down to myself (I'd never used a Mac until then). I did have to leave out a few features I would've liked due to it running too slow (same app rebuilt in Titanium is much faster) but overall it was a pleasant experience and the mailing list is very helpful & friendly. The only things that pushed me to Titanium were the speed issues with the more complex stuff I was doing (perhaps my fault?) and the fact that Titanium enables you to use proper native widgets rather than simulating them with jqtouch or whatever - This was massive for me but no one in the real world has ever noticed :)
