NB4540 or HTL-5140 if you want something on the balanced side.
HTC370 if you want more bass and more versatility.
No.
The reason you are getting audio delay is because of how the Xbox One is processing audio through optical. Just do a search on Google for Xbox One and its optical audio delay issues, you'll see thousands of comments on it.
I do not have an Xbox One now, so I don't know if they've fixed anything. But since you said you're still getting audio lag today, that means they haven't done a damn thing about it?
Switching to HDMI should fix things. I don't know if you should get a new soundbar yet though.
Basically 5140 is a more balanced soundbar, less quantity on the bass, less versatile. The CT770 is more versatile with more input optioins, but bass is a little too bloaty even after tuning the sub's volume.
Thanks for the advice. I can't stand it much longer because the lag totally screws up music or exercise games on the Kinect, which is my main use of it. If HDMI direct input solves that then that's a go for me. I can handle a little aggressive bass. Just need to get some audiophile's settings to tune it to a fine balance.

EDIT:
I picked up the Sony CT770 and you were right, it's really bass heavy. Dialed the bass back -3, sharpened up the mids by turning on AAC (Voice left at 1), turned on the Clear Audio Sound Field, and it's perfect. My HDMI inputs produced no audio delays whatsoever.
Highs are sharp, Reduced bass punches warmly, and the mids (with AAC) are clear. Ip Man's fight scenes are ear candy with this. Loving it.
i haven't tested it with a 5.1 movie yet though. But since my TV's in the hall and not a square room, I don't have too much hopes on simulated surround.
