There’s probably also service benefits but I luckily haven’t had much trouble (though some people swear by them) so the only time it mattered to me was when a bored driver took me out in a
Porsche to play on the tarmac at Seattle during a long layover. 
i am higher on the upgrade list for sure but I’m not sure it’s made a difference on my routes; that is heavily dependent on your flight patterns.
Wow how did you manage that? I don't even know who to ask for something like that. I just made Diamond and hope to have a tight connection one day just to ride in the Porsche just once lol.
I do like boarding with the First Class. This is valuable for having ample bin storage, assuming I couldn't clear into Comfort/First class with its dedicated storage.
