OP - your problem is that there’s too much choice between loads of very good options. It’s pretty likely that nearly any of them would be excellent. So you can’t choose.
It’s a bit like when I’m trying to buy a new kettle, or toaster, or microwave. The reality is that pretty much anything I could buy, at least from a reasonably reputable make, would be totally fine for years. But as soon as I find one I like, I check the Which reviews and the Amazon reviews and the Mumsnet reviews, and they all disagree with each other and bring up things I never really cared about in the first place but start to obsess over. I could just buy the first one on the list and it would be fine.
I suggest you get yourself asap to a camping showroom where a load of reasonable options are pitched up, and go and have an actual look at them, if you haven’t done that already. Most of the better known makes will all be great. There are always a few reviews complaining about this that or the other, but they’ll generally have loads of great reviews from satisfied customers.
Then when you’ve looked around in real life, work out what really matters to you - what size do you want? Blackout rooms? Air or pole? Three rooms or two? (We like two large rooms rather than one bigger one and two small, and that always narrows it down).
We had an outwell Montana 6 - excellent. Then a kampa bream 4 air tent - smaller for shorter breaks. Now we have another larger outwell, with air poles - the Montana is still fine but we wanted a bit more space and air poles. Love the quick and quiet doors. I’d recommend pretty much anything outwell do, Vango always look mostly identical to outwell but alternative brand, and the kampa one we have is also great.
