Mine would be B&M because of their stand up, floorless and flying coasters. I hope we get one in Aus soon!!!

You missed out on a few there, but Im going to say both B&M and Intamin because they have been doing some really good rides lately. But i also like GCI and Maurer Sohne, and Mack seem to be pretty solid too.

Gotta love Intamin, havn't been on a S+S or a B+M so my experience is limited, and the best out of the coasters i have rode is superman, therefore i had to vote for Intamin.

I gotta give it to MACK. Love the rides they do, and those ride systems have so much potential its not funny (a really well done water coaster would rock pretty hard). We've seen with Scooby Doo the tip of what can be done, so I'd love to see more of their stuff. Of the others, well love the rides but hate the height requirements involved with those rides. Would rate B&M and Intamin pretty evenly, with Arrow then Vekoma.

B&M, Intamin and GCI all have given me a great ride.

Mack is good too, Expecially Scooby Doo (Only mack I have been on) But it is GREAT, so Mack would also be a favorite, I want to go on Euro Mir, at Europa Park though, that looks awesome, But if Scooby Doo didn't have all the theming, it would possibly be a very average coaster.

I'm sure it's pretty obvious but I'd go for MACK too. They're an innovative company with so much potential. I've been on a couple of their Wild Mouse coasters - both having themed vehicles - and one of their water coasters. They're always bringing out new products and new ways of delivering totally immersive story experiences.

Has anyone seen that Mack at the Amsterdam Dungeons where the station is the lift? what happens is that you board the vehicle but there is a wall directly in front and behind you, and then the whole loading room just lifts up, IMO it is a pretty cool idea. Another little manufacturer i like is Wiegand, the coasters they make may be small (and in some peoples eyes not even a coaster eg RCDB) but i really do like their alpine coaster, its fast, safe, fairly cheap and makes good use of the terrain (Terrain coasters are actualy my personal favourite) and i hope some day i can ride one.
