Center point and barska are the 2 lowest IMHO.
I could probably think of some that I would rate lower, but I agree that I rank those two below Tasco.
And I have also never had a Tasco 'World Class' or 'Pronghorn' fail, that I can recall. Rimfire and airgun scopes, yes. But not the World Class or Pronghorn. They're cheap. They're nasty. But they usually work, and I'll take one over a cheap Bushnell any day.
Ironically, Bushnell owns Tasco now.
I dunno. I've got a Banner I've had for close to 40 years and it was used when I got it. It hasn't failed yet.
Different company. Different materials. Different manufacturing facilities. Different assemblers. Different scope.
The Bushnell we know today is not the same Bushnell of the '70s and '80s, no matter how much they advertise being in continuous business since the '40s.
Some of their other products are still reasonably decent. But I won't touch low end Bushnell scopes any more.
Even the Elite 4200 that I gave a shot about 12 years ago ended up failing me in the middle of an elk hunt. And I wasn't happy with it before that, either. It was inferior, optically and mechanically, to two Redfield Revolutions that I bought at the same time, but it cost three times as much.
