Boox Note Pro vs Likebook Mimas

[Spectralis]

I've searched forums and Youtube for comparisons between Boox Note Pro and the Likebook Mimas but came up empty. Has anyone had any experience of using both and, if so, what are your conclusions? I'm particularly interested in:

1) Screen durability for writing (Note Pro glass vs Mimas ???)
2) PDF annotation ease.
3) Speed/Power (4GB vs 2GB Ram and CPU differences).
4) Quality of front light.

The Note Pro (including case) is £!60/$210 more expensive than the Mimas (including case) here in the UK. Is it worth the extra cost? I own the Boox Max 2 and Likebook Mars and like them both.
