Las Vegas - Best helicopter tour company?

hello erverybody,
what would be the best company for a helicopter tour to the grand canyon (maverick, papillion, sundance, etc.)?

thank you for your help!

I haven't done any of them - but the Papillion office was based out of the same building as my office when I worked in Vegas and the folks there seemed genuinely nice and caring. Can't tell you about their services (at the end of the day, they're all probably pretty much the same - just depends on what type of helicopter they fly & what you want to ride) - but they were good people.
