Running on standard software stacks, WordPress can serve itself amply on any hosting account. But, WordPress Hosting gives you an edge.
If a plugin is just bad, it’ll break on any site. But, there are high quality plugins that just require a powerful WordPress hosting stack. This is where your hosting matters most.
When your hosting stack is designed from the ground up to provide the best WordPress experience, the result is faster, more secure, more reliable and overall better than a standard hosting package.
