Yeah, the Construct event system is a lot more powerful than MMF's, with more advanced functions and loops, and you can do subevents.
Are you an MMF user already and just trying Construct as an alternative, or are you trying to decide between the two?
MMF has the obvious advantage that it's finished, has a lot of users, a lot of examples and a lot of documentation already out there. But that's not a benefit of the software, per se, just its age.
Construct also has an awesome physics engine being grafted onto it. While similar plans are underway for an extension in MMF, I don't see how it will be as powerful (because it has to be a plugin, whereas Construct can handle it a bit more directly).
