I've got three currently ~ Kobo Clara HD, Kobo Glo & an old Pocketbook 360+. I've kept (but rarely use) the old Pocketbook purely as it was so compact, had a hard cover and at the time was one of the few eReaders that could read both prc & epub (less relevant now with Calibre about). The Glo has a slightly temperamental on/off switch but otherwise is fine for travel use. The Clara I use when I'm at home. I've gone through a number of others too over the years but I've worn them out or knackered them
