Razor leaf is far inferior to Vine Whip when attacking, although they'll both make key defenders (especially now that all other grass pokemon are so nerfed, Venusaur should be more valuable on defense).
I'd go with the 93% one. Excellent IVs. The moveset lends itself to both attack and defense (solar beam for finishing move on attack, razor leaf for defense). Although if you've evolved two Venusaur maybe you see a lot of Bulbasaur? Trying a third time to get Vine Whip may be worthwhile if you can get the candy and just evolve a higher level one from the start (although you'll hate it if you get another RL or a VW/Sludge).
