Without any knowledge on the details of both implementations: scalability has two dimensions, vertical where one server can handle more requests and horizontal where more servers can be added to serve requests. In recent years focus has been put more on the latter and for that the performance of a single node isn't as important as for the vertical scalability.
To my understanding vertical scaling has limits which is the servers limitations as horizontal scaling if infinite since unlimited servers can be added

That's true but total horizontal scaling is very hard for systems that need some kind of consistency properties
