All of LGA.
While 35X isn't the best, you do have access to the general terminal and the AC and can generally just show up ~20 minutes before the flight. On the CRJs from this gate, early boarding doesn't really matter as there is no FC / have to gate-check, so I'm fine with the bus (though would love the new terminal once it's finished!).
The LGA B terminal just has terrible food options, all of the gates are usually crowded and many of the nicer loungers (eg. Centurion Club) are before security. I guess this is more terrible terminal rather than gate, but it is what it is.
