Cannon towers are AWESOME on all-green challenges. I'd build a few temporal/laser combos for the effect, a few infernos or meteors for masses where it fits the map, and tons of cannon. They can shoot over one another, unlike guns, and their range makes them really good. It ranked me #82 on all-green fire control (the first with cannons: 2 meteors on the top-left island, 1 on the topmost's left corner, 1 inferno on the left of the strip strip, 2 temp+laser on top-right island and to the right of the strip, rest cannons).

But in general, yes to red guns. Especially on poison core levels where you can't afford fancy mazes and you need to kill everything fast.
