Help me choose a 5 channel amp please

Anyways, I guess I'm now trying to decide if I should keep my JBL amp....with the previous mentioned fitment issues. I do have a JL XD400/4 laying around...I thought about using this amp, and purchasing a separate amp for the sub. So it looks like I have a few options based on just that...Also looking at options mentioned by other members.
All in all, the goal is to go in the direction of best overall SQ obviously...Seems like there are lot's of options out there, which is going to work best and why? The list could go on, but I'm certain there's an overall best/ most efficient setup. I could be over complicating things, but hoping it all pays off in the end.

Ill do the pg for 250 shipped if your interested, only til the amp I want sells

Alright need honest opinions here. Will I gain or loose SQ going from the JBL GTO to Phoenix Gold? TaylorFade on the forums claims that JBL amps are an "SQ steal" which is what pushed me towards the jbl. Keep in mind that the JBL is class A/B on 4 channels and D for sub. So confused for some reason...sometimes I wish I wouldn't over-complicate certain things,but it has its benefits.

The pg will sound about the same I doubt most would even notice the difference. The jbl is nice no doubt and more power for subs

So from what I am gathering....

It wouldn't necessarily benefit me "SQ wise" switching amps....just personal preference and dealing with the size.

It does seem like I could benefit by going with different speakers up front or switching the rears to something less aggressive.
