A2 Hosting is one of the leading hosting providers, and they have been for a number of years. Arvixe used to be very highly ranked, though they have fallen short in recent years, which is unfortunate. When looking at the two companies side by side, it is really not much of a competition at all. A2 Hosting is ranked far better by users, they serve more regions, they have more hosting options, and a more impressive list of features available. To put it simply, if you have narrowed your options down to these two hosting companies, A2 Hosting is the clear winner.
