This is something I strongly agree with. Per your educated recommendation, it definitely does seem seem Buchholz' Psi is ideal for ordinal comparison purposes.

Perhaps to condense space people could also adopt a color-coded OCF system, such that Madore's Psi could be red: \(\color{#FF0000}{\Psi(\Omega)}\), Rathjen's Psi could be blue, and et etereca. I nominate green for Buchholz's by the way. :3
