You typically don’t think of Klay Thompson and Jordan Poole as highly similar player archetypes.
Yes, Thompson and Poole can both be considered two-guards, but with opposite levels of versatility. Thompson can slot in as a three or four with a higher degree of switchability on defense. He isn’t at his ideal offensive usage as an initiator; him handling the ball and dribbling has a short lifespan in terms of efficiency. The longer he has the ball in his hands, the less likely a possession will end with a bucket.
Poole has the ball-handling chops to be a decision maker on the ball.
