What is the best degoogled tablet for an artist

what is the best tablet for iodeOS, GrapheneOS and LineageOS

• with smooth stylus support that is as good as apple pen
  • palm rejection
  • pressure sensitive stylus
  • works well for krita / excalidraw / xournalapp
  • latency
• at least 16GB RAM and 256GB storage

---

For iodeOS, it doesn't seem to support any tablet device officially

• iodéOS official supported devices - iodé

---

For GrapheneOS, the only choice is google pixel tablet (or maybe pixel fold). However

• pixel tablet have latency issue
  • based on Google Pixel Tablet Review - YouTube
• pixel fold does not support stylus
  • workaround This Stylus Pen works with the Google Pixel Fold - YouTube
• Can someone share their GrapheneOS pixel tablet experience on krita / excalidraw / xournalapp?

For LineageOS

• What tablet+stylus+LineageOS has the best performance?
• What tablet+stylus+LineageOS has the best balance between price and performance?
• Can someone share their stylus experience on krita / excalidraw / xournalapp?

Sincere thanks

EDIT:

• ipad
  • I realize my title is confusing, when I say degoogle I really meant completely Open Source and private.
  • ipad with network disabled?
    • not feasible in my use case
    • apple backdoor is highly likely in my opnion
    • Of course I don't have any proof, but I would assume it runs camera and microphone without us knowing even when the network is disabled. The data is collected and processed locally and send to apple server when network is enabled
      • speech recognition is integrated in many app and sold to advertiser
      • I doubt apple could resist the temptation of money and the threat from government not to activate microphone and camera without us knowing
  • apple is as disgusting as google
• but of course if this is the only choice ...
