When building control panels and reversing starters I like to use solid because you can make it look so much neater as the wire holds it's shape to the route you lay it. I build a few lift station control panels for septic dosing systems. They are a lot of fun but I wouldn't want to build them all day every day. As far as terminating under a binding screw on a device goes, the reverse twist works fine and captures all the strands. Personally, I haven't used side wired devices for quite a while. I use back wired with pressure plates such as the BR15 or 5252 duplex devices.
