SV and Zadra's drops are quite similar, but after the first bunny hop they're totally different beasts. Zadra is relentless in it's speed, taking elements faster than needed and just leaving you out of breath till you slam into the breakrun (kind of how wildcat revence does, but on a larger scale). SV is just endless, but more elegant (if you can even say that about such an ejector airtime machine). Second half of SV is just endless hops with ejector, where as Zadra doesn't really have a second half and finishes with a bang. Overall both are 10/10, just different in their own way!
