Hi
As I have only been using AUctiva for less than a year I don't know what the other editor looks like as I opted for the new one when I started. I can tell you from what I've read here that 2.0 is more powerful than its predecessor. That said as will all HTML editors it has its quirks don't they all)
I would suggest you give it a try a I believe it is a lot more feature rich than the earlier one
