Verdict
The clearest difference is in-app purchases: iDevTools at none against MQTT Spy's 1. iDevTools also leads on ads (none vs shown) and chart position (#23 vs unranked). MQTT Spy's advantage is device support (4 vs 2) and iOS requirement (10.0 vs 17.0). On price and update cadence there is nothing between them.
