The best 55 gallon fish tank?

i was wondering the same thing a few weeks ago so i did some researching because i plan on getting one also...i looked at the aquaculture and i seen it had a 20/40 filter in a 55 gallon tank so im not sure how well that will filter 55 gallons of water through it and the baulbs give off way too much heat and not enough adequate light..my tank rose from 68 to 72 when i left them on a few days..which obviously is a drastic temperature change for fish (friend has one of these) and the top fin and aqueon seem to be about the same..aqueon looks like it comes with a bit better of a filter...and tetra i've never used because the first filter i bought from them started stinking after 3 days..i work at wal-mart part time and they have a descent stand to go 4 the 55 gallon aquarium for like 80 bucks instead of paying 150 somewhere else so i may go with it..not sure..i'll get 10% off, so i'll save a bit!
