I would prefer to use Debian if it was more stable. It worked fine on my workstation but if I try to use it on my laptop it would not ever resume from suspend making it unusable.

I think Ubuntu has the benefit of the large user base making it more likely that your problem is solved.

My laptop is also a 5 year old thinkpad x1 gen 4 so it should be supported, and Debian is the only linux that gave me this problem.

Odd, I own this exact laptop, and haven't experienced any suspend/resume issues on either debian 10, nor 11.

While unlikely, it could've been that the kernel version was too old or you were missing non-free drivers for something? On my experience, if it worked in Ubuntu, it would work on Debian, and if it didn't, using the latest backported kernel would solve it.
