A comment section on HN is probably the worst place to get this sort of answer. People buy relatively few fridges so you'd need hundreds of replies to get enough statistical power. This is on top of the problems that reviews have, like non-response bias.

edit: you can see this in action right now. There's one glowing review of whirlpool and one scathing review. I'm sure they're both honest, but what conclusion are you going to draw from that?
