Verdict

The call

UDictionary Translator and AI Translator Ultimate both sit at 4.6 stars, but that hides the real split: 100% of AI Translator Ultimate's written reviews are positive against 59% of UDictionary Translator's. AI Translator Ultimate also leads on ads (none vs shown). UDictionary Translator's advantage is ratings volume (9.3K vs 40) and iOS requirement (11.0 vs 16.0). On price, rating, update cadence and in-app purchases there is nothing between them.
