i’ve had great luck with the RLV chain tools.
The cheap one from Fastech Racing works well. Be careful not to break off the tip when tightening it, and if you do ask them to send a replacement and they might. They did for me!
Ditto the RLV is much better than the cheap one Comet sells.
They are not perfect though so I always carry a spare, along with spare pin screws, etc.
