I own a Tige' 22V so my opinions may be somewhat biased, but I'll try not to be. I've ridden behind the 21 foot Maristar, which is the same as the X-10. Here are my opinions on what you were interested in:
Best wake with least amount of weight - The only way to tell which wake you would like better would be to ride behind both. I have ridden behind the Tige' 22V and the X-10/Maristar with 1500 pounds of ballast. The Tige' wake is much steeper than the Maristar for starters. Some people like a more rampy wake, some like steep. The Tige' wake is also very, very hard, which gives you a bucking pop, where as the Maristar/x-10 is bit softer. The Tige' will take less weight to get big, but the Maristar could probably take as much weight as you could throw in it. My opinion is that they are both good wakes, but I prefer the steeper, harder wake.
Quality - Both quality boats in my opinion. I've owned on Mastercraft and two Tige's. Fit and finish on the Tige' has really been improved recently. Mastercraft has been high quality for some time.
Handling - the 22V handles really, really well and the TAPS really helps this is rough water. I didn't drive the Maristar enough to know how well it handles. The one thing I have heard is that the Maristar does not have skaggs on the bottom like most ski boats, but I don't know how that affects the handling. In fact, I can't even verify that. The best thing to do on that is test drive.
Room - both have tons of room. 22V may have a slight edge on storage because of the 102" beam.
Depth - The '03 Tige's are really really deep. I had a '00 21V and my '03 22V is probably at least 6" deeper.
Good luck and make sure test drive both!
