How do you know if they're a good app reviewer?

Would you more trust a reviewer who jumps apps as often as they change clothes or one who hasn’t changed app in years? The one who always changes probably is probably too interested in novelty over real usefulness, but the long term user might be too stuck in their ways. I saw a forum discussion with defenders of certain reviewers locked in verbal battle with each other. It made wonder if you really can achieve unbiased reviews. I guess that’s why I try to find a tool I like and then work out how to get as much value out of it as possible. Obsidian may well not be the best of these connected notes apps (and I may not be using the “best” plugins) but it works for me and I’m happy with that.
