If it’s infinitely adjustable, you’ll learn to achieve micro drops with it that allows you to maintain some pedaling power, but lowers your CG just enough to corner a bit faster, clean a technical climb, or go over moderately short but steep enough down hills. I’m not always a full up or down dropper post user, I find positions in the middle all the time that are very usable. I’ll drop the saddle completely out of the way on really steep sections or when jumping. Actually find that getting the saddle “just low enough” on certain descents is actually better than getting it all the way down.
Another hidden benefit with droppers becomes more apparent on longer rides. An ever so slightly different pedaling position is really nice on a big day.
You’re way late to the party, but welcome - give it a chance and enjoy it.
