Snapzu seems like it wants to bring it's own uniqueness to the table, Voat seems just to want to copy reddit. Voat looks pretty unappealing (visually) and the community seems more toxic over there. It's simple as that for me really.
Same. Voat just seems like a Reddit clone, whereas Snapzu differs from Reddit in a lot of positive ways. It seems like a much less vitriolic place than either Voat or Reddit, so far.
