I spy with my little eye… a foot! Lol
I like 45’s, they give more area for glue adhesion. Plus, in a situation like this, where you are removing joint area, this method keeps the joint areas equal, making it ultimately stronger than a butt joint that’s been “whittled away.” Only problem with them is that if you aren’t super precise, the fit can be off. Looks like you are rather precise.
