Same for me, if I'm putting any kind of quick connects in a semi-permanent location to make for easier gear or valve removal, I like Festo push connectors. At wing joints that are frequently disconnected if I can't make BVM EZ-air connectors work, I have never had a problem myself with the Robart twist lock connectors. I don't like the aggravation of the pictured style that requires multiple turns while I'm precariously balancing a wing and trying to hook things up at the same time.
