Best cartridge for SME 5 Tonearm?

I think the question is what cart matches up well with the SME V, not what cartridge people like. When that is considered, the list shortens quite a bit.

Yes absolutely, I know that the V and SMW12 will work very differently with different cartridges based on the length. I need the best mechanically working cartridge for the SMEV and only then, after I can make choice on the preference. Thanks for that point.

The Benz LPS or the Benz Ruby make a good pairing with the SME V arm. A few here, including myself have used that combination with success

Anyone any experience with Dynavector XX-2 Cartridge. I was told that this combination is stunning by and SME Guru.

...I was told that Ortofo (I am currently using the Ortofon) are not the best matches for this arm due to the design,....

Absolutely not. Ortofon cartridges are a superb match with the SME tapered magnesium arms. The Cadenza series, a NOS Jubilee and the stunning Windfeld are all perfect on the SME arms as are the older style models such as the Rohmann and the MC5000.
