Ramshorns and Malayan Trumpets coexist in a nice balance. From my experiences, the Malayans tend to outcompete the Ramshorns and they almost go dormant. If conditions change a little, the Ramshorns are back briefly before again being outcompeted. A nice little backup plan. Eventually balance is achieved and sustained.
Clown, Zebra, Leopard Loaches etc. are great at thinning the snail population but often wise enough to not wipe it out. The first time they almost wipe out a population they seem to farm them strategically afterwards. They are my preferred method of thinning snails when that is desired.
Physical removal is unlikely to do more than thin the population. If you can physically remove the entire population successfully you deserve an award for patience and dedication! With this strategy of thinning I would suggest placing a food they like on a little saucer for a while, remove when covered in snails. Some Lettuces or sinking pellets draw the snails in quickly.
I have never seen a nightmare snail scenario where the tank wasn't an ecological nightmare to begin with. In a balanced tanks the snails find balance too.
