i have a kobo libra 2 and it's served me very well. I sail the high seas for most of my books and I haven't had any issues at all loading content onto it, it's always fast and responsive, and I cannot understate how nice having physical page turn buttons is. highly recommend if you can find one, though theyve been mostly discontinued to make room for the color model that came out recently (would not recommend the color version, color e-ink is very hit or miss right now and it's not worth the screen quality trade-off).
