You're kind of comparing grapes to grapefruit
Picotope (3 gal) comes with:
*aquarium (heavy glass)
Fluval Flora (7.9 gal) includes:
Fluval Ebi (also 7.9 gal) has everything the Flora has except:
* no co2
* no tweezers
* no ferts
...instead it includes
*shrimp supplements & food
I've got the JBJ Picotope and love it. The light is fine for low to medium but I called Catalina and had them send me this
for $15 + shipping with 6700k instead. After I fab'd some legs it looks great and 13watts lights up the tank.
I've got a some Red Cherrys, about 5 guppies and a female betta splendens and it's moderately heavily planted.
Long story short: If you want a complete kit turn-key (just add H2O and livestock) go Fluval at about $100 +/- for twice the volume.
If you want something smaller but just as nice and be able to make your choices about substrate, use your own ferts or shrimp food and save more than half the initial cost, go Picotope. (DrsF&S have it on sale for $42 right now)
