This is an easy comparison largely because SiteGround is one of the best-ranked hosting providers around. FlyWheel, however, does not have many users yet, so they are still building their reputation. They appear to be doing a good job so far, but they have a long way to go before they can compete with the likes of SiteGround. In the end, the exceptional quality of the hosting features provided by SiteGround makes them the winner of this comparison.
