I would also add that since OVH own and operate a large physical network[0], they can't really be compared to a hosting-only provider like DigitalOcean. This isn't 'like for like', and is only marginally useful for ranking either company.
Also, for those of us looking for server space to serve a primarily Western market, OVH and AWS are most definitely comparable. AWS have a huge and impressive range of features, most of which I simply do not need (though I'm a happy OVH, AWS, and DO customer because I'm not one to put all my eggs in one basket).
