Those two frames are for sure more comfortable, but they don’t really directly compare to the Ezone 100, Pure Drive etc.
The Speed MP, I would compare more with Percept 100, Pure Strike 100, Blade 100 etc.
For my game, I really need the easy power and stability these typical tweener frames offer.
On a different note, it seems the new Prince Beast 2024 model have something that sounds very similar to Yonex Serve Filter. They seem to call it PVS II.

Translated by google translate:
“The new material, polymer elastomer, has been installed in an expanded range from the grip to the shaft, filtering out the impact and unpleasant vibrations when hitting a ball, and transmitting only comfortable hitting information to the hand. Achieves unprecedented super shock absorption and super vibration absorption. ”
