2023 Update: I have not used TSOHost in a long time since one of my site was unexplainably hacked a while ago, and it took support a very long time to assist me in wiping it out and restarting anew.

I have since moved to a different hosting service.
-------------
I've been with TSO Host for a bit over 2 years, using their Cloud Hosting.

I've been with at least 2 other large web hosting providers in the US, that were top rated, and they almost always failed to honour their uptime promises. I've been into web development for 8 years now.

TSO host is quick to resolve issues, and instead of having your site down once a month for over 5 minutes...you may have 1 outage every two years with TSO...and they take it seriously, solve it quickly, and then let you know what they're doing to prevent something similar from happening.

I have outside audit on the uptime% on the 4 websites that I run, and it's always in the 99.5-100%...whereas with the other providers, it was more in the 85-92%.

TSO host is not the cheapest hosting, but those few extra pounds or dollars, will save you a lot of headaches down the road.

I have a Cloud Hosting, Linux/Windows hybrid platform and host both ASP.NET and PHP (Wordpress) websites.
