Im in my 50's
Tinder is ok and not a hook up site. Dire men can't message you. But even if you swipe left, they pop up again. Beware the rogue 2345 miles away men. Despite your search criteria, if a man has liked you, he will show up, no matter how far away he is
Bumble is ok, but the man at least has to have something interesting on his profile to send him a message about. If you swipe left, they are never to be seen again.
Hinge, I find no-one sends a message and you have to really. But the sound messages are amusing at times.
POF - has scammers and catfish, but it is useful to have if you sit incognito in the background to double check someone. It gives more information. Men who you would never entertain can message you if you are not hidden.
Badoo - I didn't find anyone nice this time. But did once find a LDR a few years ago. They have a lot of profiles on from men who died years ago. I found 3 once. I'm good at background checks!
Overall, I'd try every one of them. The same men are on most. Bumble is my preferred choice. They all have their strengths and weaknesses.
