SB Whois Scraper or Email Grabber? Which works best for you?

Hey guys,

I have recently tried to compare the performance of ScrapeBox Email Grabber and Whois Scraper for a set of 200 websites. The email grabber returned me about 50 emails (less than 2 minutes) whereas the whois scraper returned about 150 emails in 10 minutes.

That left me wondering, which can be more beneficial when it comes to outreaching/cold emailing?

The whois grabber more or less gets me the blog owner's info, which I feel is good for outreaching, whereas I am not really sure…
