The 80's are better, because they are Axiom's top of the line, that does not mean everyone should get 80's or that 60's aren't great. This is true with all speaker companies.
Blu, coming from someone that has owned both for over 2 years each, don't lose any sleep if you decide to go with 60's. Yes there is a difference, but I would not call it huge, especially if your listening at 1/4 watt.
