owned 2 suburbans (both bought new) during my youth over a 15-year span (granted they both had a LOT of miles out on them over those years). Both had major mechanical issues/engine problems shortly before getting replaced. They got a Sequoia nearly 20 years ago and it's still going strong.

The Suburban was bigger, but I would say the Sequoia has been plenty big enough,and the reliability factor would top the scales in favor to the Sequoia for me.

As far as the other models - I can't really say because I have no experience with them.
