The verdict
For a small team that is starting out, pick Meta Ads and nothing else. Run a small campaign for at least a week, learn what a lead or sale costs and only then think about automation. Meta also offers its own automated rules and Advantage+ campaigns, and they cost nothing extra.
Pick Revealbot, as an addition and never a replacement, when your spend or account count has grown to the point where a missed day costs real money. It also suits you if you run several ad platforms and want the same logic applied across all of them.
Write clear rules, start with alerts before actions, and review the execution log regularly.
