Who has put time into finding good smart money wallets and results

I have always just scanned adapted to narratives, noticing fake volume, bundles etc and have honestly never put actual time into searching for good wallets to track other than tracking some good traders from twitter but obiously these guys are tracked by hundreds of other people lmao. But I am just curious those of you that do put time into finding good wallets smart money whatever it is. Is it worth it have you seen success from it and if so are you just scraping through gmgn and searching for consistent traders or are you using some sort of code that scrapes pnls to get lists of top performing wallets? Let me know!
