In deciding whether a camper is right for you or not, I think one of the first things you have to ask yourself is where you want to camp. I've had a popup and a 19-foot travel trailer and wound up selling both of them not long after I got them because I realized that I couldn't get them to some of the sites I liked - especially the 19-footer. (Duh)
Campers definitely have their benefits: The ability to keep things stored and always ready to go, good shelter from extreme weather*, comfort in the form of air conditioning/ducted heat, full galleys for cooking, electricity, and better protection against "critter invasions". But they also obviously cost considerably more than even a high end tent. On top of that, there are maintenance costs (tires, leaks, bearings, wiring, etc.), storage fees/storage space on your property, licensing fees and higher fuel consumption on the tow vehicle.
Tents offer their own benefits. I put an asterisk on the weather issue because, with the right tent, it's possible to withstand pretty much anything a camper can except maybe high water. This is why I own five different tents so I can pick one to suit where I'm going, who I'm going with and what weather I'm expecting (and haven't spent anywhere near the cost of a camper). The biggest, a Kodiak 10 x 10, has heat, a cot, a table, room to move around and 12 volt lighting. It's withstood some pretty nasty wind and rain, too. And, to be honest, I'd rather be in that tent in a blizzard than I would a camper. If snow gets too bad, I can break camp, throw everything in the truck and 4-wheel it out without much of a problem. I can't say I'd want to be pulling a camper in conditions like that. But, like I said before, the biggest advantage of a tent is the ability to get to sites where you simply can't take a trailer. All it takes is one deeply rutted road or seriously sharp turn or steep hill to put a stop to things when you're pulling something behind you.
All that to say, my preference will probably always be with tent camping. I like the solitude of getting to that far away site and don't like RV parks where you're parked within earshot of your neighbors.
