Verdict
The clearest difference is in-app purchases: GPU Arena at none against Electrician RF Field Toolkit's 2. GPU Arena also leads on update cadence (every 2 days vs every 2 months). Electrician RF Field Toolkit's advantage is ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
