Well from my personal experience the tablet > mouse, especially when you use a screen tablet and the screen has a rough texture.
The control is way better than with a mouse.

I use an XP PEN ARTIST PRO 22E and I really like it. It's also good as a second monitor.

I was used to Wacom Intuos or even the Bamboo back then. Learning to draw with a mouse is not impossible but there are sweeter
options in my opinion and when you have the funds to make your life easier: ***do it***

Those are my 2 cents.
