The newer versions are much better. Take the time to customize it a little in the user prefs and you can get it to act in a more familiar way, like SU. Nonetheless, it will still have a learning curve. I much prefer the newer versions, I've been able to accomplish a lot of work in them that would be painfully difficult in SU and then import that work into an SU project. I still consider myself a Blender beginner though. It's difficult to figure things out sometimes, like many free apps there is limited documentation on how to get it to do what you want and much of the information is for older versions. Very frustrating at times.
