It still has more modern tech than current tourney and functions better.
My advice: Don’t buy Tourney. Quality starts at Deore.
Theres nothing wrong with the tourney either. Other than the rider, whole other plethora of combinations dicating shift quality such as chain, chainring teeth, cassette teeth, condition of wires etc.
Tourney is not ideal for aggressive riding ajd shifting but will still do so reliably for years of maintained properly like any other derailleur.
I've used the altus, alivio, and deore all extensively. They all worked fine.
