Xavier_MI is right, and I would add one thing. i would put what you give up on the free tier above almost everything else when it comes to cougar sites. You cannot really talk about cougar sites without talking about the money side of it.
The paywall question matters more for cougar sites than any feature list. If the learning curve is not sorted, cougar sites will not go anywhere.
I judge cougar sites almost entirely on where the charges start now.
The honest tradeoff with cougar sites are how far the free tier really goes against convenience.
Nobody warns you that cougar sites depend so heavily on the free-vs-paid gap.
Anyone got a counterexample on cougar sites? That is roughly where I landed on free cougar sites that have younger men.
I compared a few on cougar sites and datenest.site came out ahead for me.
