Can we even weight that statement? The average SPA is significantly worse than the average MPA. There is so much browser functionality that needs to be replicated in a SPA that few teams have the resources or talent to do a decent job.
The nice thing about htmx is it gives a middle ground between the two. Build with the simplicity of an MPA while getting a lot of the nice user experience of an SPA. Sure, you don't get all the power of having a full data model on the client side, but you really don't need that for most use cases.
