Lock ring tools with guide pins are great. That is why I have two: one with a pin sized for QR skewers, the other with a pin sized for 12 mm thru axles. I find that a cassette wrench works better than a chain whip because one does not have to arrange the chain whip in a way to prevent the chain from coming loose from the cassette. I recommend this cassette wrench:
Cassette Wrench - 1670/2BI-US – Unior USA.

Fully agreed. The key aspect is to arrange the respective handles of the two tools (e.g., cassette long ring tool on breaker bar and cassette wrench / chain whip) about 30 degrees apart so one can use both hands to squeeze the handles toward each other to loosen the cassette lock ring.
