Synth as master keyboard. Suggestions?

Maybe flip things around concentrating on the features you seek. Do things like poly-aftertouch, MPE, keyboard splits, built in sequencers, arpeggiators, keyboard size / feel, controller features, CV, etc, matter to you ?

List out what you want and then picking will be easier.

Here’s a new option for keyboard “synths” that can also act as a controller. I quote the synth part, as it doesn’t become one until you complete it, but the nice part is what that synth is, is completely up to you ! And you can change that as you change as well.

The Cre8audio NIftyKEYZ.

I like the keyboard splits, multi-channel CV output, the arp and sequencer built in, and the price, among many things.

Even the Eurorack parts you add can be part of the controller.
