Best mouse for Dorico?

I have Intuos Pro 10. It is twice as expensive as Apple MTP II and support multi-touch gesture and has more features ( buttons and touch ring). So I assume automatically it is a better choice than Apple’s MTP. Plus, I see @John_at_Steinberg has it but doesn’t touch it and uses slimblade (hidden on his right side).

I am right-handed. Do you place it on the left side or the right side?

I assume you use it with touch on mode and not with its Pen. Aren’t I correct?

The pen is too thick and to do a keyboard shortcut, I need to put the pen down next to my keyboard and then press the keys on my keyboard? Do you use its button and touch rings?
If so, how. I appreciate it if you could explain that.
