I'm adding two more lights (Normal Fluorescent) to my 90g tank for a total of 6 lights. I like the T8 34Watt bulbs but am wondering if T12 40Watt bulbs would be more beneficial (allow greater variety of plants) or is the difference negligible?
Difference between 2.6 and 2.27 watts/gal?

I would say the difference would neglible. The T8's have some advantages to the T12's that might even make them superior to the T12's. Assuming you have the same bulb, etc.
I've heard that T8 bulbs provide more light than T12s. It has something to do with less surface area of light or something.
