My opinion is that MMF2 is klik n' play v2 with a diferente interface while Construct is a buggy version of what MMF2 should've been in the first place. I must say that it's amazing to see Construct evolving so quickly, as it's very far from the broken and imcomplete piece of software it was some time ago.
Is it too late to ask for a comparative list of differentiating features that sets MMF2 and Construct apart from each other? I've taken a look at Construct and discovered something new to figure out that's a lot like MMF2 but with what may be more "programmer-friendly" terms slapped on buttons.
I'm sure its as good as MMF. But I'd also like to determine what's the best thing for me to use when starting up on a new project. Stick with the old, or bring in the new?
