The B737 is as good or better than any other current or planned narrow-body or wide body jet produced globally...
Even navigation wise, not really. As Denti says, no curved approaches with IAN, it won't tune an ILS for you automatically (something Boeing introduced on the 747-400 in the 80's), no autotuning of appropriate VOR/NDBs en-route for position check, etc. Plus, you can't do a single-engine Cat 3A autoland with single AC source - unless you have an HUD.
No doubt 737 is a very nice airplane, just not a very modern one.
