Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
ESP RainMaker Classic holds the better App Store score, 4.4 against 4.0. That said, the two scores are not equally well evidenced: ESP RainMaker Classic has 12 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 30% of ESP RainMaker Classic's written reviews are positive against 100% of HTML & Markdown Viewer's, so the app with the better star average is not the one people write more warmly about.
