We had a Clickteam Fusion and Construct 2 comparison thread a while ago, and for those who would like to compare the two, but lacked the financial resources (or , what better chance than getting Fusion with the newest Humble Bundle deal.
I still very much prefer Construct 2, though. I feel Fusion is targeting a somewhat different market. But it is certainly nice to have access to both tools - especially when you work on a Mac as well as Windows (since Fusion seems to work on Mac now).
And a free copy of Install Creator is actually quite handy as well.

*Edit* after investigation, this is the standard edition of Fusion: meaning a restricted distribution licence (the standard version requires that you include a "made with Fusion" logo in your work).
