Siteground has multiple types of hosting; shared, cloud and dedicated. All of which you can host WP on. I haven't used a lot of hosts, but I agree with Ismail, I've found their support and speed to be the best by far.
Any time I have a question or an issue, I pop on to their livechat, which usually says I'm around 29th-30th in line but someone's chatting with me in literally seconds, and the problem gets fixed either right then and there or within a day max if it needs to be escalated.
The only issue I've ever had with them is that they don't support ASP.NET sites as well, but can you blame them?
