I looked at both and none really are quite up to thumb expectations. Even though a ten gallon vert is used by some people and they have success doesn't mean you can't go bigger than you already have. The more space the better! The thumbnails will thank you! I know you didn't quite say this but it came to me from the question you asked. I think you should redo it planting wise (Background looks nice) this tank if it doesn't have frogs in it, (if you are going the the thumb root) its great for a trio of leucomelas though. The reason I saw "no" is because first there is no leaf litter, 2 there is very little broms, and 3 there is a water feature. There are stories of thumb drowning in water features. Also think of hiding spots, thumbs love hiding spots! I can speak from experience.

They love their broms and plants too. So don't be afraid to heavily plant the thing. Just don't load it so you wont see anything or else you over planted it and the plants cant grow. Some nice cheap methods for the thumbnails to breed and hide in are film canisters (I don't know but I love em) and jungle pods. Also since you are looking into thumbs, I find it easier to use a front opening viv. Thumbnails are much faster than the leucomelas your used to. DO A LOT OF RESEARCH! I did research for 1 whole year before getting my first frogs which turned out to be imitators. They are very cool to watch. And now looking back i'm glad i did it because in the long run, I successfully breed my frogs! It was so cool to see an imitator come out of water. They are just plain awesome frogs! Do the research and you will be fine.
Also slooow down! This hobby is very addicting but you dont want to get burned out to fast. Some people get a lot of species and then just get bored. Take it slow. I got my frogs almost a year ago and Ive yet to get another frog. Im waaiting till I can get my ultimate favorite frog
