It depends on your usage patterns, presumably.
In my case, I ended up accruing $100/day w/ Claude Code (on github workflows) so Max x20 was an easy decision.
Pro seems targeted at a very different use case. Personally, I’ve never used the chat enough to break even. But someone who uses it several times per day might.
ETA: I get that the benefits transfer between the two, just with different limits. I still think it’s pretty clear which kind of usage each plan is intended for.
