Rock-solid server to have a deal with ...

[Childs]

Servers from legionbox.com and planethoster.com are well-balanced and they cost not much but I'm not sure which way is better to go?

Industry Reputation. Long-established hosting providers with good track records are often more reliable. Avoid hosts with a history of frequent outages.
Take a look at CentoServer.com dedicated servers. The hosting solutions cater to a wide range of needs, from bloggers to large enterprises.
Their quick server response time improves my site’s user experience.

The mentioned companies - legionbox.com and planethoster.com - are good and reliable enough to sign up with.
The services here are inexpensive and of a high quality. These companies  maintain a high level of service and their technical support are real professionals.

The hostpro.com provider has VPS plans with good technical characteristics, including SSD NVMe storage and unlimited traffic. It comes with a convenient choice of server locations - the USA, the Netherlands, and Poland. There is also support for several popular control panels, including CyberPanel and DirectAdmin. It is nice that daily backups are stored for up to 30 days, which gives you confidence. Everything works stably and smoothly.
