How comparable are tirzepatide and semaglutide on the evidence available?

For reference: tirzepatide · semaglutide.

The comparison I want does not seem to exist anywhere in a form I can evaluate.

I have read the arguments for each and they do not engage with each other.

What does each option buy me, and what does it cost me?
