Stable server provider ... what should I do?

[Dexterity]

Well-balanced servers from legionbox.com and hostsailor.com are attractive for me and I am in two minds which way is better to go and why?

Pretty good dedicated servers are here:

Also sometimes you do not need to have the whole dedicated server and in this case starting with VPS is something what would work really nice for you in this case.

I'd draw your attention to servers from decent hosting providers: hostingsource.com and datapacket.net.
Great features overall hosting features. Different web-hosting plans to cater for different budgets. Positive and quick support response.

They have good pricing for the servers which are based on Intel.
I think it is very good deal to start with.

Accounts from allwebhost.com and centoserver.com are worth trying due to their top-notch services.
They are polite, fast, professional and offer unbeatable prices!

Everything depends on your goal. If you are looking for DMCA-free streaming servers (https://www.swisslayer.com/) - check swisslayer.com.

Take a look at GTHost.com instant servers (https://gthost.com/instant-servers/). The connection/download page speed is very good, I can gzip my content, no problems at all.
Anyone looking for a great host, look no further! For just $5/day you can enjoy the full experience of dedicated instant servers then, once your trial is over, you’ll have the option to choose a different trial or to start a contract.

I jump at the opportunity and recommend you to look at Datapacket.net dedicated servers (https://datapacket.net/dedicated-server/). Great features. Their prices are great but not the cheapest. I highly recommend these guys!
