Landslide vs Boulder Druid

I've been following the Boulder Druid build from Maxroll and it seems to be doing well right now, and is generally fun to play (once Hurricane duration is longer than Hurricane cooldown...)

But I see a lot of posts on this sub mentioning Landslide as being the best Druid build.

My question: which build is actually better? It may be worth noting that I play Hardcore (and so survivability is also a priority for me).
