I'd avoid POF as people can just pay to message you so it's pretty awful. Don't think it used to be but it's changed a lot. Also, Match is horrible.
I don't think there is much difference between them otherwise.
Bumble, the men expect you to message first after a match as they think it has to be the woman first. But this changed a while ago so if you have a set question prompt, they can answer it and open the chat, they won't.
Hinge you get notified of a like, and people will get notified of your likes. Although I don't think it's all of them as otherwise the paid feature wouldnt be saying you can "see all you likes" if you get it. You do have to like a specific thing on their profile though.
Tinder now shows you some people that have liked you as you swipe through. Is intuitive and generally easy.
The guys who have wanted hook ups I've mostly found on Hinge and Bumble so that view of Tinder is a bit dated now.
Also, out of all the people I've been on dates with post separation, the 2 I met through real life (and not on a dating app) were the worst by a mile. They turned out to be horrible people.
If you fancy giving it a go then try and get a thick skin, read up on the things to look for, and don't be disheartened if you meet horrible people, it's most definitely not because of you.
