Agreed. In a properly managed, reasonably static, cowboy-free
environment, 'on' is fine.

I've used 'on' for L2 and L3 Etherchannels for years and can't recall
a single problem (serious or otherwise) directly attributable to 'on'.

Also agreed. I certainly wouldn't rule out using LACP for future
deployments. Link aggregation is much more common these days and
particularly when interfacing with servers, introducing some more
brains into the equation can only be a good thing.
