Really depends on your style of camping, your views on security etc. Time plays a bigger role with everyone's busy life too.
We used tents years ago, then moved to a soft floor camper, then a Jayco Dove and now a Coromal XC poptop. Our camping varies from staying in one place for a week to traveling and moving every 1-2 days.
With the soft floor you always had to set everything up - bed, kitchen, table and anything else you wanted. A pain in the ass when you are moving most days and a lot of time tied up in setting/packing up.
The Coromal is bloody fantastic for us now. For example, we got delayed in our travels in January and pulled up around 8pm when it was dark and we were buggered. We just popped the top and that was it. In bed in a few minutes if needed.
Years ago when we had the soft floor camper we got lost somewhere around Katoomba and finally found our camp around 8:30pm. It was raining so we cooked under a gazebo we found. Didn't stop raining so we just slept in the car and it was crap. Wished for a caravan that night!!!!
I still enjoy boys trips in the swag, got a 3 night-er coming up in a few weeks. Swag on a stretcher under the awning, simple and quick packup while on the 4x4 tracks.
I must admit, the soft floor camper really felt like camping. Having the van takes that feeling away a bit but the van allows us to get away more so it's a win for us.
