A legit SEO Tool that you think is good

I've seen many SEO tools being used and advertised online and I tried a few too, albeit none of them seems to be that much of a help and all of them seem to be giving different data on things such as how many times a keyword was searched, the CPR of a keyword, how much impressions it gets and such. Is there any tool that you guys know is actually good and effective from your personal experience? I feel like I cannot trust the internet anymore, there are way too many tools with way too many scam data, it seems.
