RefreshRate's advantage is ads (none vs shown). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Mobile Master sells 3 in-app purchases, starting at $0.49 per month and RefreshRate sells 4 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.
