Wilkommen Murali and thanks for joining up here. Munich is a lovely place to live. I used to live in Stuttgart so not too far away 
As for the cameras they are quite different since the RP has a full-frame sensor and the R10 a smaller APS-C sensor. The R10 is much newer and has a better focusing system. There's are pros and cons to each as usual. I'd recommend taking a look at this article for a better understanding of how they compare:
