I can sympathise with your decision making process
We have gone backwards and forwards about 2000000000 times LOL..
So I bought an oztent ..that lasted till the planning stage and was sold on
Then we decided stuff it I will tow a trailer ..that lasted till we could not hire at the right time/price.
So we went back to the previous trips we had done and looked at what worked and what did not.
We travelled with 4 of us in the tent Rumpig has posted the video of. Some advantages of this tent are that it packs flat into a square so it fit,s into a roof rack bag very easily and is surprisingly light weight. The disadvantage can also be this point if you want to pack it anywhere but the roof.
After 10 years ours has finally started to show some signs of wear but for the price $299 we have had a great run from this tent and I would highly recommend it.
All that said we are now needing a replacement and after considering our prev trips we wanted the simplistic design but a little more flexible in the packing options as I do boat trips as well as car based.
So we have decided on a Blackwolf 300 lite -- but NOT the plus tent. one thing i wanted to get away from was extra bits to set up, we simply want to POP it up and be done ..after looking at the PLUS tents we realised that they were no quicker than the touring tent but 3 times the price, the only other downside of the touring tent was entry/exit in rain as the door slopes backwards.
So that's where the Blackwolf 300 lite came out in front. it goes up very quick , no extra poles has a very simple front awning that requires no poles /peg /ropes and is a 3x3 mtr square sleeping area. Blackwolf have 2 options with the fly , we opted for the very small front awning as opposed to the 3 pole design as that is just more to set up, we mulled over this point but came to the conclusion if we are going away for 3-7 nights we always put a tarp up or some other shelter so was the full awning needed on a touring tent which would require 3 poles and ropes to be set up every night in order to use the fly- we thought No and once again looked back on our touring tent and realised we managed with that for years so the small awning is a vast improvement on that. So in summary we just wanted an improved version of what we had without much else. This is the one we have settled on and at under $700 is reasonable in price.

Hope that helps with our decisions but spending big on a quality tent only to take just as long as the one thats 1/3 of the price was the trap we nearly fell into, so work out just what your after and then look at that, I am not a fan of rooftop tent for the points listed above.
