For me, weight, ergonomics and page-turn buttons are more important than an excellent screen. Also I prefer 7'' screens over smaller and since getting my first reader with the warm light feature (Oasis 3) that's a must-have as well (for reading in dim lamplight during autumn and winter. I don't like bright lights, not even a bright reading lamp.)

So I sold my Voyage, despite its having the best screen of all my readers. I found I no longer liked to use it. Now I mostly switch between the Oasis and the Libra, sometimes the Nook as well (it's heavier than the others and the software is much poorer, so not my favorite. Still, I don't want to sell it. It has most of the features important to me - buttons, nice big screen, warm light, and it's quite comfy to hold.)

The Libra has better ergonomics than the Oasis, but the Oasis has a better screen. As to software, both have their pros and cons. The Libra has an excellent integration with Calibre, more features and is far more customizable. The Oasis is faster and has global search.

As to price. I'm not rich or even well off by any yardstick, and I'm very price-conscious in most areas of my life. The only areas where quality is more important to me than price are stuff for my cats (litter, food) and my electronics (laptops, tablets, ereaders - my TV, fridge and other household stuff are on the cheaper side). The latter are the only really expensive items I own.
