I really prefer bright white pages because I use color in all of my spreads. I also hate the look of white-out on off-white paper. This is my current notebook, which I have used since September and have 0 complaints about: https://www.amazon.com/Tekukor-Journal-Hardcover-Notebook-Sketchbook/dp/B07PH3R2W3 However, it is a dotted page and I couldn't find it in graph. If you're not doing watercolor, you can get the cheaper 100 GSM version, or if you just want to save on cost you can get one of the ones without the fabric cover.
