How much experience do you have with Adobe products? If you have used Photoshop, or some of their other programs in the past you should be able to pick up Premier. If not, the learning curve is pretty steep.
Also, are you looking at Adobe Premier Elements or the full-blown version? I can't comment on Sony Vegas, but I have heard good things about it.
I agree. ALL programs have their hiccups and quirks. Adobe's learning curve can be steep if you allow it to be. Break it down slowly (perhaps purchase a premiere classroom in a book) and learn it tool by tool, feature by feature. I taught almost 200 10th graders, most of whom never had any prior Adobe experience, Photoshop this past fall, and by the end, they were turning out some VERY impressive work (movie posters). Just take it slow, and you will do fine. Can't comment on Vegas, either, but like HuntingBry, I've heard good things about it.
