Personally I don't think it is fair to compare the panthe rlake cpus ending with a 5 with those ending with an 8.
The cpus ending with a 5 are more similar to those ending with an U in the past while the panther lake cpus ending on an 8 are more comparable with the former H cpus.
And of course the X7 is much faster en better, but is it worth paying the premium price?
