I was very close to buying a 5110 R last year at a very reputable German shop,But I wanted to try the P first.I always liked white metals more and thought it would match my casual outfits more.
For some reason the platinum supply on the market is not as much as it used to be.After I tried the 5230G,I have to say 5110 is the best modern WT reference for me at least (Limited series not included).
Best,
Ahmed
