I'm using a dual rec and I borrowed my buddy's JVM 410 and they're completely different, so you can't claim one is better. If you already have a cab, you might want to get a head that matches the speakers. JVM and V30s sound horrible...hate to point out the obvious.
The cleans are better on the JVM, but I was expecting that. The reverb was horrible! HORRIBLE!!!!!!
The JVM is no more unreliable than any other modern amp and only sound bad when dialed by someone with there eyes and not there ears.
I have both and they are not the same at all. Which do you prefer apples of oranges?
