Preact would solve most (if not all) of the performance problems listed in the executive summary of the post (build time, time to interactive, memory usage, and maximum data set size). It doesn't seem like a terrible comparison to mention a framework with the exact same api as the one the team in the post was using for 2 years before adopting htmx.

It's a pretty short post, but a lot of it boils down to the fact that the team is using a single language throughout the whole stack (Python), which allows everyone on the team to be a full stack developer. Like I said, if you're against writing js then htmx is probably a better solution for your team.
