From my experience, it all depends on how you are going to use it. Standard pop ups (we have a 2005 Rockwood pop up) are excellent for campground camping. They are also usable on dirt/gravel roads and field/festival type camping. Benefits are relatively light weight, easy to tow, tons of room when popped up and a nice airy feel that you don't get in other style trailers. Drawbacks are that they are not very durable, cheap frames, etc... and they do not take kindly to off camber camping locations. The RV manufacturer off road pop ups address the frame issue, which adds weight but is needed. You are still a gravel/dirt road camper, not trails. The one standard manufacturer out there that might address some of this is livin lite with some of their models, such as the one that is Jeep branded. It is pricey, but made for how we desire to use it.
My wife is tired of our pop up. The work of set up, take down, etc... and dealing with wet canvas. We actually have looked at several alternatives, but have not come up with the right blend, so for at least this season we'll be in our pop up or in our little utility trailer/truck tent mash up.
