What RSS/Mail Client do you use?

Personally i use Opera Mail Client on my laptop to view both my Emails and RSS feeds, but i need one that can sync both my Email addresses and RSS feeds across all devices without having to re-login all addresses again on a new device.

Any suggestions?

I use Microsoft Outlook. It does both so well. Been my go to program for the last 3 years now. However, I am not sure about syncing across devices. I always set up my email accounts afresh everytime I am on a new Windows PC (that has happened only thrice in the last three years). I transferred/imported my feeds from another client I use from time to time, QuiteRSS, so that was/is always easy.
