Would think you want the shortest most direct route to clean full 12 volt power to your coil. And if you have an electric choke carb, you do not want to pull power from that 12 volt coil feed to power the choke as it degrades it making your ignition do funny things.

I feed my electric choke from the Wiper motor Blue wire. 12V on ignition.

This is protected by a circuit breaker in the Wiper switch. On my 69 at least.

Worst case, if the choke shorts I loose wipers until I can un-hook the choke. Not a fan of connecting it to the primary ignition circuit!
