The clearest difference is rating: Source Audio Neuro 3 at 4.4 against BOSS Effect Loader's 3.5. Source Audio Neuro 3 also leads on in-app purchases (none vs 8) and update cadence (every 4 weeks vs every 5 months). BOSS Effect Loader's advantage is review sentiment (42% vs 21%).

Both are free to download. BOSS Effect Loader sells 8 one-off in-app purchases. Source Audio Neuro 3 asks for nothing beyond the download.

Source Audio Neuro 3 holds the better App Store score, 4.4 against 3.5. That said, the two scores are not equally well evidenced: Source Audio Neuro 3 has 51 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 21% of Source Audio Neuro 3's written reviews are positive against 42% of BOSS Effect Loader's, so the app with the better star average is not the one people write more warmly about.
