Verdict
The clearest difference is in-app purchases: Rackmaster at none against MD Preview's 1. Rackmaster also leads on iOS requirement (13.4 vs 16.6). MD Preview's advantage is ads (none vs shown) and update cadence (every 3 days vs every 6 weeks). On price and device support there is nothing between them.
