Verdict
The clearest difference is in-app purchases: 压缩专家 at none against Live Caption's 5. 压缩专家 also leads on review sentiment (63% vs 47%). Live Caption's advantage is ads (none vs shown) and rating (4.4 vs 4.2). On price, ratings volume, device support and iOS requirement there is nothing between them.

Live Caption holds the better App Store score, 4.4 against 4.2. Both are backed by a comparable volume of ratings — 76 and 43 respectively.
