Why is the Tupolev Tu-154 so unpopular with passengers?

I certainly don’t see why it would be the best plane, but I still wonder how some planes such as the Saab 340 or the Fokker F28 have higher popularity with passengers in the green-bar range compared to the Tu-154.

Because the Tupolev has a bad reputation due to numerous accidents. By the way, almost all machines from the former USSR.
