If you have the money is say get a fluval g6. It's around $380, but it's really nice. I've seen one in person and I wish I had one for all of my tanks. If you can't afford that then get the fx6. They're nice too.
IMHO dont even put the fluval g6 on your list. With your setup I would also look into the eheim 2080. If you want to go all out- classic eheim 2262 is a tank.
