From what I’ve done and seen, texture painting and sculpting are what you’re mostly gonna be using it for (and other similar things such as weight painting), otherwise a mouse is just as efficient in my experience. This is also due to the fact of the tablet I’m using (Wacom Intuos) seems to be a little on the ol’ sensitive side and sometimes struggles to differentiate between a tap and a drag (not to mention the drivers are as of now rather sensitive with Chrome so it can be a pain to navigate websites with it, rather irrelevant if you focus on one thing when using your tablet). I prefer using my mouse on things such as hard surface modeling, but this is mostly down to personal preference such as preferring right clicking over left clicking which is something you’ll be doing a lot of in HSM and is rather clunky with a stylus.
Overall I’d say unless you’re doing things such as sculpting a bunch it’s probably best not to get a tablet solely for Blender (but fortunately this wasn’t the case) because there just seems so many things that a mouse is more or less the same at doing, but in certain areas a tablet can truly shine.
Glad we could help you, if you have any more inquiries I’m sure one or some of us will be able to help you. I wish you the best of luck, and look forward to what you create!
