Could you provide a source on the software updates being more frequent, as well as clarify what you mean by rM being bad at updates? rM has been pushing out updates fairly regularly this year, especially if you include their beta channel.
Fair enough, maybe this has changed then. When I last tested and looked into the rM2 in depth (~2 years ago), it was completely different. The software was lacking basic features and there wasn't any communication at all on rM's part.
Also, the Remarkable devs are notoriously bad when it comes to software updates and sharing their plans for the future with the community. Meanwhile, the Supernote people even share their Trello boards over on Reddit -> https://Reddit.com/r/Supernote
The Supernote, admittedly, is not as hackable yet as the Remarkable but 1) official software updates are much more frequent and 2) there are plans to open up the device to 3rd-party Android apps.
