Venusaur vs. Exeggutor

Vine wip is better than bullet seed.

Just based off experience, Venusaur seems bulkier. Venusaur is also poison, as opposed to psychic, but at this time, psychic seems like the better combo.

Venusaur's Vine Whip gives him the quickness that no Exeggutor will ever have. Even razor leaf is faster than any of Exeggutor's quick moves.

Actually, I think Bullet Seed isn't that bad actually.
Bullet Seed is one of the highest EPS moves in PoGo, though 10% less EPS than Powder Snow. It charges Solar Beam really fast, and Solar Beam just wrecks anything weak to grass.

I think it comes down to the Exeggutor having the higher attack stat, making its solar beam hit harder.

The Eggys are really powerful and are great for raid bosses and the first round of taking down gyms.

For rounds 2&3 of taking down gyms I like venusaur because VW and RL are fast and hit hard. It'll kill most things before they get a charge move off, so 1 can pretty much mop up both rounds.
