I've been using Outlook (formerly Hotmail.com) for a while and I've found it better than *cough* Gmail anytime of the day. I usually don't use outlook on pc/mac so I don't know if the new complains about advertisements are for real but from mast past desktop experience, I would say its a bit sluggish yet conviniently presented. As for my mobile experience I have never faced an issue. Been using Hotmail since 2007 and had a Gmail account since the same time period, deactivated my gmail account around 2014 I think.
