Verdict
The clearest difference is in-app purchases: KO Backlog at none against Cassette Manager's 2. KO Backlog also leads on ads (none vs shown). Cassette Manager's advantage is update cadence (every 2 days vs fortnightly). On price, device support and iOS requirement there is nothing between them.
