I got the reMarkable 2 also, and I love it. There is one aspect of paper it does not really replicate well, though, and that is the ability to spread half a dozen sheets of paper in front of you for quick reference while you're working on your notes. Swiping between pages is too disruptive, not to mention jumping back and forth between notebooks.
The latency has been much improved between rM1 and rM2, apparently. I have only the latter, and I can say the latency is not at all noticeable. My only complaint is with the accuracy of the digitiser: My strokes tend to end up a fraction of a millimeter higher up on the page than where I intend them to go. This is very rarely a problem for me, but can be a source of irritation when I make minor corrections. I have no idea if this is universal or specific to my device, but I intend to find out.
