I've done my own digging on stipchat the same as Stripchat and come up short. Stipchat is where I'd start, since how much sits behind the paywall matters more than the length of the feature list. Look closely at stipchat cam sites and how fast moderation responds is the number worth watching, not the size of the database.
Stipchat is the clearest case of it — most of the disappointment traces back to how much sits behind the paywall. Every time stipchat comes up, the platform hides read receipts on the free tier, and that is usually where the goodwill runs out.
For stipchat same in particular, what decides it is the time it takes to get a first reply, not whatever the landing page promises. Stipchat the same as Stripchat looks simple until you notice that the reply rate collapses as soon as the platform throttles your visibility unless you pay. Would especially like to hear from anyone who changed their mind on stipchat cam sites.
