To me the answer is NO. For the same reason you mentioned about the VST babel vs HW: convenience (or lack of).

Having many pieces of equipment to manage (stand/desktop space, cables, mixer, different UI, difficulty to integrate them, .....) is inconvenient. And this fact offsets any possible marginal gain you might have in this or that sound.
And after all, above a certain threshold, nobody will ever notice the difference. The realism of the sound itself is not even important, what matters is the beauty/appropriateness of the sound in the context of the song.

Take for example some Italo Disco hits of the 80s. The piano sound was pathetic if compared to today’s standards. But those tunes are nonetheless masterpieces and sound great even today, some 40 years later.

But there is also another consideration to make: are 3-4 k€ arrangers (and premium products in general) worth the asked price? Probably not.
The much higher price, if compared to the mid range (normal, for the masses) model is not justified by a corresponding higher quality. It is astronomically high on purpose, just to catch the wealthy people that will pay any price just to have the best. Even if they are barely capable to play with a single finger.

Instead of having a 4000 + 200 $ arrangers, maybe a single 1000-2000 $ one would be better.
