Both are free to download. EBook Viewer sells 1 one-off in-app purchase and TTReader sells 1 in-app purchase, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
TTReader holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: TTReader has 10 ratings behind it against 1, so its average is the more settled of the two.
