Mack are far better and offer many more diverse elements than Intamin does IMO
Many Intamin rides get a rattle over time, Mack's rides generally do not.
Intamin's best creation by far is Maverick, it boggles me why more parks haven't purchased similar coasters.
Forgetting Gringotts, 13 and their vast amount of flat rides?
I just don't see that MACK are up there with B&M and Intamin. Yes they have 4 or 5 decent looking attractions but Intamin have plenty more (past and upcoming). It's all well and good saying that a lot rattle but that's because the oldest MACK is 8 years old. The comparison is pointless so looking at how ICONic (
) Intamin really is there is no world in which I see MACK as a whole being more 'superior' - you're comparing a company who are in the infancy of thrill coasters to a juggernaut. Whilst I'm also not the biggest Intamin fan I still see them as superior to my favourite manufacturer, but again it's a case of a new company vs a juggernaut. That's not to say in the future this will change, but right now I don't see it - which I think is a fair stance to take all things considered.
Anyway, seriously back on topic!
