I usually research something a lot and then end up getting two or three different kinds to try. For example, a couple times now, I've gone looking for a new computer mouse and ended up buying two because I figured I'd hate one and like the other but I wouldn't know until I tried both. I don't have a first mechanical keyboard because I bought two when I first started out because I wanted to try both of them. On the other hand, if something is recommended to me, I'll just buy it with little research because I've already decided it must be the best. Or if something has a million 5 star reviews, I assume it's the best.
For kitchen stuff, I probably wouldn't give it a second thought.
