I have long been Chrome on everything, but decided to try switching to safari (primarily on my MBP) in the past year as I've been using it on phone/tablet for awhile now and generally have been fine with it - still Chrome at work, but iCloud keychain is quite nice as others have said, and the synced history, and all of that - just like you'd get with multi-device Chrome... only downside is Chrome on Mac still seems to do a much better job of blocking ads than Safari, even with an ad blocker, so occasionally that will be an issue
