I am new to the Nord-World and will soon upgrade my rig to a Nord Stage 3, which I am already very excited about.

a) which of the above mentioned options makes more sense in the long run (i.e. which of the two is preferable to use as a master-keyboard)
b) which midi-controller would be a good fit for each of the two options
Perhaps someone has recently gone through a similar decision process - I'd love to hear your experiences to help me make the right call (which is quite hard tbh, cause both options have their pros and cons)

Many thanks and cheers,
Tim
