I have a couple Boox devices right now and have had Kobo and Kindle devices in the past as well as iPads but I kinda feel those go in their own category. The Boox devices are fast, easily the fastest eInk devices I've used and are extremely flexible thanks to the fact that they just run Android. You do have to fiddle a bit with the app optimization settings because apps aren't typically designed with eInk in mind so you need to filter out animations and set refresh modes. But it is super nice to just have whatever available. The Kindle app, Libby, Google Play books, Pressreader, etc. The built in software is very good for PDFs especially in comparison to the junk Amazon and Kobo put on theirs. It's OKAY for ePubs/AZW3 but it has some rough edges and bugs but you can just use another 3rd party app so it's not a huge deal. Note taking software works well IMO too. Kobo still has a better built in ePub reader in terms of rendering but devices are slower and it's more annoying to get books on and off. As for Kindle there's very little reason to buy one unless you're certain you're going to play in their store and are happy with their limited font and formatting options. Send to Kindle is probably the best feature but you can only send ancient KF7 mobis or like txt files. You can put PDFs on a Kindle but it's a horrid experience, Kobo is slightly better especially on the new models. I've heard Remarkable's suck at ePubs and it seems like it from videos and I wouldn't use an iPad for reading books as it's just too distracting IMO. If you mainly want PDF support or want flexibility with regards to what you can do and are okay with some rough edges get a Boox, if you want good ePub support and it to "just work" get a Kobo.
