It all depends upon your criteria.
For all 'round even-tempered commentary, with analysis and supportive citation to facts, it is tough to beat Prebennorholm; MX5Boy does good job of presenting the d'nunder perspective. Superfly has the acid wit, he charms the ladies like no one else (how'd he get all that Mojo? And why won't he share it?); and he has a proper appreciation for all things Lincoln.
If you're looking for the best insightful "from the inside" posts on the airline biz (pilot's view), Doug Taylor (sorry I cannot recall his handle, but its something like DC9Cpt) is a boundless and unselfish source of information and advice.
And, as much as it pains me to credit anything with "Ag" in it (
), I always enjoy reading posts from TxAgKuwait.
MattD (along with 'Fly, above) is a fountain of trivial knowledge on open-reel tape devices; and boy can he hold forth when he gets his fur up on some topic or another.
I could go on and on. There are a big bunch of interesting folks here, from all over. But one thing is certain: if you want to see a thread die a quick death, just let me post in it!
