ReceptionRating · Positive reviews · Number of ratings

Converter holds the better App Store score, 4.9 against 4.5. That said, the two scores are not equally well evidenced: Converter has 981 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 94% of Converter's written reviews are positive against 100% of Ultimate Convertor's, so the app with the better star average is not the one people write more warmly about.
