Man, I've been down this rabbit hole before! The best e-ink tablet for drawing really depends on what you prioritize—pressure sensitivity, screen size, or software flexibility. My top pick is the 'reMarkable 2' for its paper-like texture and minimal lag, though it lacks color. The 'Boox Note Air 2 Plus' is another beast with Android flexibility, letting you use apps like Clip Studio Paint.
But here's the thing: e-ink isn't perfect for fast, dynamic art. It's amazing for sketching or note-taking, but if you need layers or vibrant colors, you might miss an iPad. I doodle on my 'reMarkable' during meetings, and the tactile feedback is unmatched—just don't expect Photoshop-level tools. For pure writing and rough sketches, it's a dream.
