Provided that that matches your preferences, sure. Not if it doesn’t.
There are plenty of realms to choose from, and all of them have the same version of the game. 
We have some population information available to us from sources such as https://wowclassicpopulation.com/, and ironforge.pro. Those give us a limited subset of population data, but may be somewhat helpful in selecting a realm to call home that matches one’s preferences.
Additionally, there are server-specific forums, listed under the general forums as well as server discords, which can also be helpful tools in finding a community that suits their preferences.
Good luck
