SiteGround gets high marks in all the discussion groups I follow.
They are a little pricey but you get what you pay for.

NGINX-based caching, SSD-drives, PHP 7, CDN, HTTP/2 available.
Choose GrowBig or GoGeek plan at SiteGround and you get WordPress-specific features, free SSL, priority support,
Again, this hosting service gets high marks in all the discussion groups consistently.
I am now using this hosting service myself and have been very satisfied so far.
You can get WordPress preinstalled as part of your WP hosting package, just tick the right checkbox during the checkout process.
All WordPress hosting accounts with A2 Hosting come with WordPress preinstalled. You can also install new instances of WordPress through Softaculous’ one-click installer.
I am recommending this hosting service over Bluehost because what I hear in the discussion groups about Bluehost service and downtime bothers me.
Bluehost shows up on google searches for best WordPress hosting sites.
Don't be fooled...they pay for that rating.
The company has been bought up by EIG Hosting Brands – who now control 80+ hosting companies. In my experience the support not up to my standards. And the WordPress Install tool to be avoided, it's very flaky and results can be erratic. ( The who, what, when of-Endurance-international Group (EIG) )
Bluehost provides inexpensive hosting – if you decide to go with Bluehost, at least pick the Pro account. The do provide Dedicated IP & free SSL for WordPress site on the Pro account.
I do use Bluehost and lately have had real problems with their service, including a higher amount of downtime this year. I monitor all my accounts via UpTime Robot. I'm migrating all my accounts to InMotion, SiteGround and A2Hosting.
