Why it's the pick
ICANN Lookup is the official registration-data tool from the group that coordinates domain names, so results come straight from the registry and registrar with no ads or upsells, and it also looks up IP addresses. The catch: most owners' names and emails are now hidden for privacy, so you often get only the registrar, nameservers and key dates.
