Verdict
The clearest difference is ads: ToolZ at none against StackSum's shown. ToolZ also leads on monetization model (free vs ad-supported). StackSum's advantage is update cadence (every 5 days vs every 5 weeks). On price, rating, review sentiment and ratings volume there is nothing between them.
