Renthal srs4 chain & sprocket kit

Need a new chain and sprocket kit.
I have been looking at this kit with molybdenum steel front sprocket and hard anodised 7075 Aluminium.
Has anyone got this type of chain and sprocket set?
How many miles have you done?
Is it worth the extra over an x ring chain?
These chains are meant to be sealed for life so the drying out of o ring and x ring chains does not happen
Is the rear sprocket upto it or should I stick to steel?
I would be interested to hear some opinions (especially if you have one)

Would your insurance tell you ? Just wondering as new to things that are new would anything extra on parts every lower price of insurance told no by mine

I've had good use from my ek chain, comes with a 2 yr unlimited mileage warranty, always use renthal sprockets, much better than steel :)
