For managed WordPress, probably Flywheel & WPEngine but I'm not certain of their scope of what they cover/don't cover.

In terms of the plugins, what specifically don't you want to manage? As long as you're not installing a bunch of junk and keep them updated, you should not have any problems with regular web hosting. Most problems stem from poorly coded & exploited themes/plugins.

All of my websites, PHP sites and Wordpress sites, are all hosted on Namecheap.
All of my sites used to be with Hostgator but after they we're purchased by EIG, quality of support degraded and so I transferred all my sites to Namecheap.

I recommend take a free trial at Cloudways Platform for WordPress Hosting.

What Cloudways does is optimize and setup all the necessary software on the DigitalOcean and Amazon EC2 servers. You don't have to worry about installing Linux, MySQL, PHP, Varnish, Memcache, Apache, Nginx and other scripts on the servers.

Host gater is a best one,im using this server its also give a good service

I run more than 10 WordPress websites using HostGator.

I have several WP sites hosted on Knownhost. They offer a wide variety of plans to fit your budget. They have 3 different control panels, cPanel/WHM, Plesk or DirectAdmin to choose from, with great 24/7 support. I've been using them for about 7 years.

I wouldn't recommend WPEngine for many reasons:
- really expensive (not recommended for high traffic websites unless you make a lot of money)
- they don't allow anything beyond a basic vanilla install. many plugins conflict and/or not allowed
- not that great of a service...so many strong competitors out there
