Well I was looking at their trajectory and first two years of the majors so lets see.
In AA Biggio had a 145 wRC+ at the age of 23 and 152 in 43 games the next year at AAA before being called up, which is higher than Schneider put up at any point in A, AA or AAA. He had a 149 wRC+ in Rookie ball.
In his two first and best seasons, Biggio hit better against RHs in his rookie season and then hit better against lefties in his second year but was still decent enough against righties (above average overall). In their first two seasons, weirdly enough Schneider has the worst split overall, with his numbers against lefties this year, which I would imagine doesn't last.
Biggio also spent a decent chunk of time in AAA in 2021 after struggling with the bat. So we was sent to AAA to work on things when that needed to happen. This is obviously a different point in time, with more seasons of service time accumulated so why would we be comparing that at all. Biggio obviously is capable of having his current utility role in the Majors, he was correct to decline it and will be going to the Dodgers in the same role.
It is impressive to be factually wrong about everything you write in a post.
I hope Schneider succeeds, I think he's a great dude, same way I though Biggio is as well. I wish Biggio had continued his solid start for us, and I hope Schneider avoids falling off the cliff. I'm just pointing out that his bat works on the margins just like Biggio's did, and we see that when he has rough stretches, like he is currently having.
He's really good at barreling the ball and waiting for his pitch, but there may be a point where pitchers adapt to him in a way that he struggles to adjust to.
