Verdict
The clearest difference is in-app purchases: Random Number Generator at none against Randomizer's 4. Random Number Generator also leads on ads (none vs shown). Randomizer's advantage is update cadence (every 4 days vs every 5 weeks) and device support (3 vs 1). On price there is nothing between them.
