I have the +2 ultra, just downloaded it last week. Upgraded from ultra, does have a few more features. So far I like it, I upgraded so I could use a windows pc or a Mac. No dongle. Stared a few years ago with 4d, have upgraded a number of times. This is my last upgrade! Lol. You can do many, many creative with the software! I just had all my manuals printed and bound so I can study in my down time! It is expensive, I can only say, buy the best you can afford because once you see all the features, you may want more and more! Yep, that's me!
