I have MTC and have found it to be very easy to use.
I only do the basics, but the other more advanced stuff is there if you're into it. I haven't had a need to do/try all the other more advanced stuff.
My favorite thing is the shadow feature, it is literally a click and your word/ title has a shadow layer. ( one thing the Cricut world is missing!)
I have always read when this Q has been asked, that MTC seems to be a bit more user friendly, I've only ever used MTC so I can't compare the two.
