I think all and all, adjustability and cost ... I think it's a great light. I use two 36" on a 56 gallon (36" wide x 21 high x 18 deep) tank with fairly high CO2 and wound up turning down the highest colors to 75 % and my stem plants still grow annoyingly fast. So for your needs, I think it will be plenty bright.
The warranty for the Fluval is also far better than for the Finnex I was looking at. Three years compared to six months.
Edit: What's your opinion on the Fluval Aquasky? Do you think that would be better suited for a low tech tank or would the Plant 3.0 be okay?
