Verdict

The call

The clearest difference is rating: Weave at 4.4 against Slack's 4.1. Weave also leads on review sentiment (72% vs 55%) and monetization model (ad-supported vs freemium). Slack's advantage is ratings volume (52K vs 1.2K) and chart position (#22 vs unranked). On price, update cadence, ads and in-app purchases there is nothing between them.
