As Greg says, the focal length of the lenses you shoot with will determine how much effort you will need to put in to polar align.
The large pixels on the R6 will go some way to disguise any misalignment but don’t we always want sharp images??
If you’re truly staying wide for the MW and have fast aperture, something simple like a Star Adventurer can be very effective, but as you have the AZ-GTi already you might as well try it
the “advantage” of the computerised mount is that you can apply software methods to assist. (I use quotes as some don’t see it as an advantage)
