Welcome to TPT.
It really depends on what is most important to you. Out of the tanks that you have listed I would go with, The Fluval Flora, because it's the biggest of them all and come with everything you will need to get a nice planted tank going. Since it is made for growing plants you get a decent substrate, lighting and co2. If you get that one, at least you will have everything to get you into the hobby to see if you really like it, without having to shop around. I'm not sure how well they do growing plants, but you can always buy a second light and get a better co2 setup if you decide to get more demanding plants. If you are open to buying the components separately. You can get a cheaper tank (petco is having the $1 per gallon sale) that is bigger and buy the equipment you prefer. Like a better co2 system, filter, lighting, etc. It really depends on your budget and the look of the tank you want. I was always told, buy the biggest size tank you can afford and have room for. In this hobby you will always want bigger and/or more tanks.
