Disadvantages of Snails in a Planted Tank

I have one snail (maybe Ramshorn) in my tank. In last 3-4 months, it hasn't destroyed any plants or cause any harm to the tank. Instead, it cleans up some leftovers and algae in glass. I am interested in getting more. Hence, my questions:

1) Do snails cause any harm to planted tank? If so, what?
2) Which ones should I absolutely avoid?

Snails help the tank by consuming decaying organic matter like dead leaves, uneaten food and some algae. The drawback is when snails eat algae on thin leaves or stems, sometimes the leaves and stems get damaged. It can also look "gross" when the tank has a swarm of them . Decrease their sources of food and they also decrease in number; that means, good tank upkeep - partial water changes, trimming off old stems and replanting the upper stems, scraping algae off the glass, vacuuming the substrate.

if it IS a ramshorn snail...there arent any real disadvantages of it...but just throw in an extra pinch of food every feeding for a week

then 1 becomes--> 5-->15-->123453241-->13535156346351

eventually...there will be a lot and then when they start dying off the others will start eating the carcasses and reproducing even more...leaving a trail of empty shells on the floor

its just a nuisance when theres a population explosion

I have an apple snail that was supposedly non-plant eating. However it turns out to be a variety that does eat plants and destroyed my java ferns (luckily the only plants as I was just experimenting before beginning). They look nearly identical to the non-eating kind, I can't tell the difference from just pictures online. So now I'm just wary of any apple snail. I also have an assassain snail in one tank that doesn't eat plants, but will eat other snails. Good if you get unwanted hitchhikers on new plants apparently!
