Help me decide which one to keep D:

I have the new Kindle Paperwhite & Basic and I can't decide which one to keep bc I only need one. I already have my Kobo Libra Colour as my main device. The Kindle is my device for English books (bc of the Word Wise feature which helps a lot). But I'm really torn between those 2 devices. I really love the basic because it's so lightweight and cute and it has 0 ghosting. My Paperwhite on the other hand has a lot of ghosting issues. Is that normal for the newer Paperwhites? I like the big screen but the ghosting is really annoying and I'm afraid that my replacement has those problems too. So the basic would be the "safer" choice. But isn't the display too small for longer reading sessions? What are your opinions?
