@Iron_Guard8In turf they aren't that great in fact it would probably go gw1 turf>gw2 turf>bfn turf. Though I do often die from potshots at low health.
Gw1&2 ops scaredy shroom is pretty effective since he has other pots that can support him while he wittles down the horde and can even shoot back into the garden from certain areas. In Bfn ops the zombies just spawn on him and he misses every shot than dies.
Putting snipers or air strike spawnables in the backyard was a nice way to farm due to their range.
Infinte ammo gw2 scaredy shroom is unbelievably overpowered and I love it. Though I never found normal sniper spawnables overpowered. In fact the only pot I found overpowered was gw1 bamboo shoot who in numbers could nuke bosses quickly.
@stukapooka I honestly never found an potted plant or bot truly OP (barring infinite ammo, rapid firing scaredy shrooms and maybe the DJ Orbital Bots), I meant more of a general idea. Bots, pots, and the mobile AI we can summon have to tow a fine line to be good enough to want to use, and not too strong to upset the balance in multiplayer matches. Of the 3, I'd say that GW2 does the best job here overall, and BfN the worst. Obviously what you summon and which bot/pot site you use matters a lot here too; putting a melee pot/bot in the back away from the point or putting a sniper bot/pot at point blank in front are not going to work well (although at least the snipers can shoot enemies while they are still far away), but getting the stats right can make a huge difference. The spawnables should matter and be useful, so too weak or too strong are both problems.
