I have snails in all my tanks. And they are all planted and I have no major snail problems. Yes, there are plenty of snails but they do not hurt my plants to any major degree. My betta tank had to snail I purposely placed in there. One died during an unfortunate gravel vacuum incident. The other is growing nicely. But since I feed my betta a small amount of food once a day there are no other snails. I even have a snail tank that I used to keep for dwarf puffers till they all dies. I feed then veggies once a week, yet they do not touch the live plants and they have no exploded in population.
Snails genrally lay their eggs on plants IME, and this may also be why you see them so often on plants. Not necessarily eating them. The ones on my plants surprisingly rarely damage any of the leaves.
