Which is the best of these MIDI keyboards if I am a beginner on a low budget?
While the answer to this question lies mostly in what specific need you have, for example, if you want to have a keyboard with the widest range of notes possible, or if you want to have as many control functions as possible, or perhaps a mix between the two, that is without leaving behind the different connections and software licenses that most MIDI controllers offer, we will give an objective opinion according to our experience in music production and thus also with the price demanded by the controllers, a kind of value for money.
