I started with Sony Vegas and later tried Adobe Premiere thinking it would be just as easy to use but I was wrong. Everything takes way longer to do with Premiere for me (different hotkeys, more steps) and Vegas is a lot easier, quicker, and more beginner-friendly doing the exact same things. However, if you're experience with Premiere, then it should be no problem for you and they are both about the same in quality in the end, I just prefer Vegas because I think it is way easier to use. If you are planning to do video making/editing related stuff as a profession, you should stick with Adobe Premiere because almost every video editing job I've looked at requires knowledge in Premiere and not Vegas.
