Cannondale component quality?

I'm looking for a new ride, and Cannondale is one brand I've been
looking at. I'm a bit curious, though, about their use of house-brand
components. For example, given a choice between Cannondale Wind hubs
and Shimano LX hubs, are there issues with the Cannondale hubs as far as
interoperability with "standard" clusters, freehub bodies, and spokes?
How do the bearings and seals compare?

Is there anything similar to look out for with seatposts or stems? Is a
seatpost a seatpost, as long as it's the right diameter? Do all stems
have to fit the same forks and bars (with appropriate variances for
diameters again), or do I need to be on the lookout for gotchas?
