Give them both a listen, it's the only way to know. For the Focal set, are you talking about the KR set or the KRX2 set? They are totally different, so it makes a difference.
I've owned the JL audio ZR components, and they were very good, but I now run a Focal KRX3 set and it's worlds apart. It uses the same tweeter as the KRX2 set - the TN53K. It's just a totally different league of speakers, you really can't compare the JL tweeter to the TN53K. Really though, the most important thing is how you install and tune the speakers. A $500 speaker that's properly set up will outperform a $1000 speaker that isn't set up right.
By the way, either set will be a *HUGE* step up from the type R components. Both sets will get louder AND play much cleaner as well.
