Best Aquarium Manufacturer?

Good evening all. I am looking to upgrade my 75 gallon to a 6ft tank. I am thinking maybe a 180 or 210-220? I see Marineland has a 125 tank and stand but was wondering if anyone else recommends any specific size tank/aquarium and or manufacturer. The tank will be filtered by 2 FX6’s that I currently have. My fish are African Cichlids, peacocks and haps to be exact. Thank you in advance!
