Go with the best. Siteground is the partner with Joomla since the time it was known as Mambo, 15 years now according to them. All of there plans are Joomla optimized and comes with the essential features needed. Siteground representatives are available 24/7 and have advanced Joomla expertise. Their speed is also great. Moreover, I love the live support, low cost, and quick responses and resolutions of all my website issues.
There is no comparison to the excellent support Siteground provides to other providers!
