I have heard the TypeX's and the MOMO's and they are both ok. The TypeX's in my opinion are pretty weak, they dont get loud enough, and the tweeters off axis response is crap. I've had alot of time tweaking the TypeX's and im very unimpressed for how much they cost. The MOMO's are a very solid speaker set and i know they are pretty inexpensive. I dont think the MOMO's really stand out at anything in particular, but they dont **** at anything either. Pretty Solid performance.
Now i have not had a chance to hear the 720prs yet, but the people who have heard them, are crazy for them. Alot of people have been saying they sound better than ANYTHING under a $500 price tag. And thats a very bold statement. For the price of the 720's im willing to be that they will smoke the MOMO's and TypeX's. In fact, im thinking about putting those in to replace my XR's instead. Hope this helps.
