I have used a really cheap 6 person tent many times.  So, I don't know that I could give you a good opinion.  Of course any review or comment would be an opinion.  Have you checked out sites like Outdoor Gear Lab (OutdoorGearLab | The World's Best Outdoor Product Reviews).  You may also find reviews under other sections here on REI or the REI Youtube channel.

Enjoy
