Kindle, Kobo or Sony ereader which one?

Im going out on a limb here because this has nothing to do with EL it is purely a toy for myself! I have been wanting one for a couple of weeks now and I can’t seem to decide which on is the best.

So can you help me please?

I am swinging with Kindle…but its a close choice. Accessories are easy to get, books are easy to get, warrenty and name is solid.
Battery life really is what they say it is! If you want it for more than just books get Kindle Fire. If you want it for just novels for your self the cheapest one will do. Note that not all have COLOUR! inportant for kids not so much you.

Really depends on what you what it for really. Do you what to use it for night reading? do you want audio? do you want color in your pictures? etc
There are lots of review videos on youtube. Try keywords like “kindle paperwhite vs nook glowlight” , kobo arc vs ipad mini" etc

Hope this helps
