Space Marine Tank choice

I need more firepower in my army. Predator or Vindicator? I think anything on a Predator has greater range, but that Demolisher cannon with a strength 10 ap 2 blast seems pretty awesome.

Depends on what works better with the rest of your army. Vindicators work better with an aggressive army list, while Predators work better with a more gunline-oriented army. As The Mike Leon would tell you, Vindicators aren't as good in 5th because everyone and their mother gets a cover save now, but I'm still a fan.

I usually run a nice cheap 85-point Predator with autocannon and heavy bolters with my army. It usually makes its points back.

This is the way to go.

Vindicators can still be awesome, but you have to have luck with the terrain, opponent and what not.
