Verdict
The clearest difference is in-app purchases: Pdf Studio at none against Local TTS's 2. Pdf Studio also leads on iOS requirement (15.5 vs 18.6). Local TTS's advantage is ads (none vs shown) and update cadence (weekly vs every 3 weeks). On price and device support there is nothing between them.
