I have to put my hand up to vote that I like snails, pond snails, MTS, ramshorns and assassin snails I’ve kept them all in all my tanks over the years.
Snails are mostly a natural addition to any tank, they give the benefit of cleaning algae off the glass, once I had a 3 foot planted tank without snails side by side with a 2.5 foot planted tank with snails, the 2.5 was way cleaner than the 3 foot, honestly I spent ages cleaning algae on tank glass on the 3 foot until I decided to add a handful of MTS and pond snails and hey presto, within a week or so, nice clear glass with minimal effort!
Also as already mentioned, MTS are great for substrate, I call them the gardeners of the fish planted tanks, turns over the soil, get rid of potentially bad AOB air pockets, and eat leftover foods and plant debris and in turn over time creates mulm in the substrate which is great for plants.
