I know what you mean, I've been through a few tents over the years, every time you take them down and put em back up, they seem to be less stableAgreed.
Unless you're willing to spend 2-3 times on a GG-type tent I kind of look at tents as disposable.
The vivosun 4x4 I use is sturdy enough and has held up to a seasons use with no issues.
