Same as Todd_H, with one difference. what decided it for me with closest cam was the everyday experience. I'd put how much to share early on above almost everything else when it comes to closest cam. I judge closest cam almost entirely on the subscription question now.
The practical side is what separates a good week from a wasted one with closest cam. You can't really talk about closest cam without talking about vetting people properly. Two people can have opposite results with closest cam purely because of vetting people properly.
That is the short version of closest cam like omegle that allows adult content; ask if you want detail.
If you want a comparison point on closest cam, tried Ezhookups.
