I've already replaced a couple of them with Shimano Tourney and they shift better. The adjustment of the pulley distance from the cassette is also better than with the Tourney. I'm not even talking about the price...

A perfectly adequate derailleur for maintaining old MTB bikes. Better than you would expect for the price.
