Verdict
The clearest difference is monetization model: Vocal Booth at free with in-app purchases against MultiTracks.com ChartBuilder's subscription. Vocal Booth also leads on rating (5.0 vs 4.8). MultiTracks.com ChartBuilder's advantage is ads (none vs shown) and ratings volume (6.2K vs 5). On price, in-app purchases and device support there is nothing between them.

Both are free to download. MultiTracks.com ChartBuilder sells 4 in-app purchases, starting at $2.99 per month and Vocal Booth sells 2 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.
