What are the biggest mistakes with useful tools in AI Influencers?

On What are the biggest mistakes with useful tools in AI Influencers?, the part about useful and tools stands out to me. I would test one small workflow first, keep the variables consistent, and compare the result before changing several things at once. The original point — "I have been exploring AI Influencers and wanted to ask people who have tried it in practice. I am particularly interested in useful tools and reliability. I would like to compare…" — gives a useful starting point for that comparison.
