To me, eink is definitely better for reading books, which is what most of those readers (Kindle, Kobo etc) are used for.
The other big advantage is battery life. I have an old Kobo Aura I got second hand on eBay. I keep the WiFi turned off, have installed KOReader and load books over USB (with the held of Calibre). With semi-regular usage the battery lasts weeks if not months. Way longer than any phone or tablet I ever had. Granted of course those devices do a lot more, but it's nice to at least very rarely have to worry about whether you have enough charge to read a book.
Like you I'm not sure of the advantages of eink for more general computing. I wonder what the (actual) battery life is like on the ReMarkable.
Like you, I have an old offline eReader (4th gen Kindle, replaced battery). My eReader lasts multiple books of use on one full charge.
I also have a ReMarkable 2. The battery lasts about 14-16hrs of on-time for me.
I keep it in airplane mode and have sleep mode disabled to prevent it from locking after 40 minutes. I turn it on around 10AM and turn it off at 5PM, writing on it sporadically between those hours. The tablet reaches a low battery state by Wednesday.
