I'm satisfied with El Capitan, so now you know at least one person who is. The thing you need to bear in mind is that these forums are like a hospital emergency room. You're only going to see people in here who have problems. The ones who aren't are like the doctors and nurses, trying to help everyone else. You also need to remember that the people who post here, either because they have problems or because they want to help those who do, are but a fraction of the overall populace that has downloaded El Capitan. You can't gauge whether or not you should upgrade your OS by what you see here. You can't predict whether or not you'll have issues because your system is not the same as someone else's system.
That said, if you don't want to download El Capitan, then don't. No one is putting a gun to your head.
