2x36 watts you'll be pruning a little more weekly,
1x55 watt you'll be pruning biweekly
It both cases you'll still need to keep up on ferts co2, and waterchanges. You can slack off a bit more with 1x55.
I like the idea of the 2x36 due to the coverage it can provide. But 1x55 watt is probably enough to get the lush growth you desire as well.
If you're really not sure, you can always purchase 2x55watt kit and run one 55w bulb, and if you decided you want more light purchase one or two 36 watt bulbs for your 55 watt kit.
Maybe someone with a 25 gallon can chime in with their experience running 1x55. Again, I think you can grow pretty much everything with this too, but the coverage won't be as great as staggered 36s.
