Best Hosting for WordPress

[Vidoyars]

I run several WordPress sites. Some are more complex than others (1 is moderately intensive).
I'd like to host all my sites on the same platform, rather than have 1 here, 1 there, etc. I can spend up to $40 a month on hosting. So a few questions:
1) Are there any "premium" shared/cloud hosting platforms out there (I know that sounds like an oxymoron, but some shared hosts are better than others).
2) Should I look at Managed WordPress solutions? Any recommendations?
I am looking to upgrade to something more WordPress friendly. (currently paying about $25/month).
What can you say about Regvps.com vps hosting solutions? Can I rely on them?

Thanks!

Just choose the host that suits your needs and provides constant and uninterrupted services and support.

Make sure to contact web host and see if they can do services for you such as restarts etc fast. Also confirm what kind of conditions your server would be kept under - that is very important.

Content Delivery Network (CDN) Support. A CDN improves site speed by distributing content across multiple servers. Look for hosts with built-in or easy CDN integration.

What are the provider’s requirements to cancel a hosting contract? What is the required period of notice?
