Scaleaway is meaningless unless you're located in Europe.
If you're in the developed world, $2 vs $5 etc does not matter in most cases. The most important factor is that your host does what you need it to do, that the network is excellent and your servers are located where you need them to be.
If you're an American business you'd be foolish to host your servers in the EU. Locating your servers in the EU opens you up to their jurisdiction, which is a mistake, you'd be unnecessarily exposing yourself to multiple jurisdiction compliance. That problem is only going to get dramatically worse in the coming years. It's not worth worrying about saving a couple of dollars over.
