Thanks to the referral code from here, I am summarizing rm2 vs kindle scribe (KS as follows) on my experience:
RM2:
(1) Better dealing with large pdf. This is a bit odd to me, since the processor of KS should be better. But when turning/jumping pages, the loading time of KS is horriable.
(2) Writing experience on pdf/notes is better. More tools are available, and it feels slightly better (marginal). No significant lag for both.
(3）Sync is close, both will take a while, but I prefer RM since it is slightly faster (marginal).
KS:
(1) Back light is very helpful.
(2) Kindle store.
(3) Discount on amazon (roughly 20% if you wait a bit).
Con for both:
(1) None of them can handle two columns journals.
(2) Cannot access google drive pdf files.

Basically, I made the decision quickly and returned the KS. I am not 100% sure I will keep RM2, but it is likely it will stay with me for a while.
You left out the biggest "con" of all for the KS, at least for me ... privacy (or the lack thereof).
amazon monitors everything you do with the tablet (or any other "kindle" device), and uses that information to build a profile to target you with advertising.
If "google play" or "firebase" are installed (they come pre-installed on most android devices), google also monitors which apps you run (whether downloaded from their store or not), and in some cases what you're doing inside those apps ... again, to build a profile to target you with advertising.
I have not seen anything to indicate that reMarkable is collecting or sharing information about how people are using the tablets (although the fact that the reMarkable Connect "cloud" is hosted on google's cloud makes me not trust it, because the files it stores are not encrypted).
