Verdict: which one has fewer problems?

Across the latest 600 App Store reviews we collected, ChatGPT has the lowest share of reviews with a complaint (21%) and DeepSeek the highest (39%). The biggest single difference is in bug complaints: 31% of DeepSeek reviews mention them, vs 15% for ChatGPT. Each app's own biggest complaint theme: ChatGPT, bugs (46 reviews); DeepSeek, bugs (92 reviews). Average star rating in the samples ranges from 3.01★ (DeepSeek) to 4.11★ (ChatGPT). Time span of each sample: ChatGPT 4 days (2026-10-19 to 2026-10-22); DeepSeek 528 days (2025-05-13 to 2026-10-22). Because ChatGPT's sample covers a much shorter period, a single recent update or outage weighs more heavily in its numbers. Samples that reach back many months (fewer reviews per day) show long-running issues rather than the effect of one recent update.
