I trust Apple more than Google.
Right now I'm using a mix of iCloud and Microsoft's services. I use Microsoft for mostly everything (email, contacts, calendar, storage, video/audio chat, search) and iCloud for extra things (photos and drive mostly). I had my email on iCloud but the web interface killed it for me. And Outlook offers push too, and soon might be offering better desktop support so it was a no brainer.
I just moved away from Google entirely last month and deleted my account. I think Apple's more trustworthy than Google or Microsoft, but Microsoft seems more trustworthy than Google.
