Based on previous post, I think food matches those from DL. Wifi is likely better on HA. Seat comfort, however goes to DL.

Airport experience, for premium passengers, is likely better with DL with possible access to Delta SkyClub (or heightened even further with future access to Delta One Lounge). Does HA have access to JL First Lounge? If not yet, AS/HA/JL joint venture will likely expand this benefit.

AS/HA still has lots of catch up to do.
