Clutch plates, Surflex or non-Surflex?

Whilst I was browsing, as you do, I noticed Triumph clutch plates for sale, both Surflex or non-Surflex types.

I realise Surflex are Italian made - is there a difference to be aware of, ie is one preferred to another? Curiosity sake only for now, but it maybe useful knowledge.

Some cheap plates are cork lined and grip better when oily, than Surflex plates.

So are Surflex a no-no if another brand is available at the same time and same price?

I had bother with Surflex plates slipping in a Triumph 650, whenever they got oily.

Not everyone has that trouble, apparently.
