Not sure this is too off topic, but I also had the large iPad Pro with the pencil as well as the smaller version (which I have now but only use for testing). I have a Samsung Tab S3 which used to be my goto machine before the Google Pixelbook. And I have a MS Surface, which while nice, is just too difficult to carry around all the time. Not a big fan of the touchscreen interface, though it is better than Mac OS ;-)

I got frustrated with the limited battery life of the iPad pencil, always running out in the middle of meetings) not to mention the crappy way you had to cantilever it off the iPad (just asking for damage). Google, MS and Samsung don't have that problem with their pens. Google and MS have batteries that last a year, while Samsung never needs recharging.

Tried Concepts but found it too structured and at the time it was more a sketching and final rendering app than a macdraw type app like neu.notes+ or metamoji. Also, I really like the ability to write characters using the character zoom bar at the bottom, plus grouping is a must as well as PDF output (vectors).

Again, I'm more interested in graphic note-taking than finished drawings...

I find these days I can sketch faster in programs like SketchUp than I can in a structured program, so I use neu.notes+ which is just fine for quick concept drawings:




It's also great for facilitation meetings with clients and sketching out wireframes because of it's GROUPING features, vector graphics and zoom control:




I tend not to draw much anymore for final artwork. Doing it in 3D is just so much faster. PLUS, MoI3D has some great EXPORT features to both AI, PDF and PNG, which can be very helpful. Not to mention exporting from MoI to KeyShot and using it's toon shader for illustration:
