I spent a good deal of time here over two different days.
My first thought is that it is very clean.
Second it's super long and stretched out and thank goodness for the people movers. So many.
I spent my time in Terminal A and wasn't blown away by the restaurants or food options and it was tough to find what was around. But, when you find a good spot you can sit and get comfy and hang out, without feeling bad. Which is nice.
Lots of seats around, lots of gates, so I feel like it has some good stuff going for it.
Even when it is busy there's still a way to find room to walk, sit, whatever.
I have some good memories here thanks to some amazing company, which might skew my opinion a bit, but I think it was a good place to hang out for a few hours waiting for a flight.
