I had Kleos, Skala and Titan i. Only the Kleos for longer and on some LP´s it sounds great. On others it is too much HighEnd to my ears.
But asking about which cartridge to buy is very difficult to answer. Problem is, that the fewest of all are not really well build.
I have a VdH Frog which was especially build for me and in my ears it sounds better than all Lyra´s i heard (EMT JSD6, Phasemation PP300, DV XX2MKII, Transfiguration Phoenix S too)
But i have had some Frog´s with fabrication defect...
I think the Hyperion is a great thing to test. My MIMC is the most neutral cartridge i ever heard.
