I have a 1816 Field Notes cover, which I carry with me most places. It holds two Field Notes, so I usually have one for work and one for personal stuff. I use them for reference, notes, quick sketches, etc. They're super easy to get in and out of the cover too so if I need to just slip one into my pocket I can do that.
At home, I have a LEUCHTTURM1917 dot grid notebook for more fully-fleshed out sketches and mockups. The paper on this is a little thin (but it doesn't bleed), so I'll probably be trying something new when it's full.
