While there seem to be quite some regional differences in the adult sizes, that Redfoots obtain, Yellowfoots generally grow bigger, which is a concern, if you are space limited.
Also, while Redfoots are found in a pretty wide variety of habitats, such as wet savannah (especially close to rainforests, that are inhabited by Yellowfoots,- they tend to not mix in nature), edges between rainforests and savannahs, rainforests per se and even pretty dry savannah habitats f.i. on some islands, Yellowfoots are a real rainforest species.
In terms of husbandry this means, that the ambient humidity for Yellowfoots should be in the 80% plus range and nighttime temps barely lower than daytime temps, while you can get away with lower humidity levels especially for adult Redfoots, as long as you provide humid hiding places.
There are probably more considerations, but the above might make it easier for many keepers to go with Redfoots.
