Disregarding the Robo Monkey's ability upgrade, does it do more raw damage than Sun God monkeys?
It's a bit hard to compute, but I'll try my best.
The Robo Monkey can pop a total of 7 balloons per shot, and shoots twice at the same time.
However, the sunrays diverge somewhat and have a tougher time hitting individual MOAB-class balloons. They also fire at half the rate of the Robo Monkey's streams.
The Sun God's streams do pierce, however, making them better at clearing out large swaths of balloons at once.
There's a lot of back and forth there, but I'd say the real advantage of the Sun God that makes me pick it almost every time over the Robo Monkey is the ability to turn it into a temple, which makes it obscenely powerful and leaves room for more towers to be placed.
I think sun god because it has a bigger damage, shoots three sun rays and you can turn into a temple you can't stop that.
IMO, robo monkey and sun god are almost the same. They are better at different stages. Robo monkey is good for farming, for single target damage. Sun god is better late-game, when you are doing temples. I get one sun god when farming, to help with bloons if needed.
As a rank 67
Fires three streams a little under every second. Sun rays are able to pierce and spread out as they go farther off the screen. (Pierce means destroy more than 1 bloon layer at once.)
Camo: No. Great on regenerating bloons.
Splash Damage: Yes.
Single target: Not so great.
Instead of shooting one constant beam like a normal super monkey, has 2 guns that can shoot independently from each other. Guns shoot whatever upgrade you have(lasers, plasma, darts.)
Camo: Again, no. Great on regenerating bloons.
Splash Damage: Not really...
Single target: Definitely. Totally anti-moab.
Here is a little trivia, just to get your mind going.
-A sun god has more popping power than an unmodified temple(although temple has camo detection)due to the fact sun gods fire three rays a little under every second and temples shoot 1 huge wave a little under every 3 seconds(in non fast foward)
-a robo monkey with no path 1 upgrades surprisingly can destroy leads with ease, although a normal super monkey with only darts cannot even dent leads. -robo monkeys are a reference to the 1987 film robo-cop. -laser monkeys cannot destroy leads.
Here is my final answer: sun gods will clear bloons with ease, so sun gods are better for taking out massive waves of bloons, however; robo monkeys are better against moab-class bloons, due to the fact they are better-suited for single target combat. So, you should definitely get a balance between the two tier 3s. Here is the ratio I use: 5:1(for every 5th robo monkey I get 1 sun god)
Robo Monkeys can dent several BFBS to nothing while the Sun God leaves some of them laying around into cermaics or zebras. A robo monkey can dent a ZOMG much better than the Sun God. The Robo Monkey is 3/5 the cost of Sun Gods, so you can have several robo monkeys instead of getting a few Sun Gods.
