I know it's not cheap, but I've really come to enjoy Adobe Lightroom, as well as the rest of the creative cloud suite. I also don't care about the social aspect of sharing my photos (comments, likes, favorites, etc...) -- so if you already have a CC subscription, don't care about social, and just want a place to post -- look into Adobe Portfolio.

Edit: I'm not advocating that you go subscribe to adobe just for the hosting! But if you already have the subscription but aren't making use of the hosting, it's definitely worth looking into. It's included in the subscription cost. Consider this my glowing review.
