Better or worse is all a matter of opinion. My order of preference of 'pest' snails is; MTS, Rams, Pond snails. MTS get the top pick because of their digging behavior. They stir up gravel or sand, releasing any possible toxic gases before they have a chance of becoming an issue. Ramshorns forage well, and if you have the common veriety, they don't eat living plant matter. Pond snails also don't eat living plants, but they lack the beauty of the Ramshorns, and the digging of MTS (Malaysian Trumpet Snail). I've got all of them, and Mystery snails too.
Ramshorns will reproduce like bunnies, given an ample food source. Don't worry about target feeding them, they are excellent foragers.
