There's a lot more to the J than that...that being said, having the automation available to use has benefits.
A. I've got about 2k hours in E-H2.5s and Js. About 1,500 of those hours are in legacy airplanes and about 500 hours in Js. I've shut down one motor in the J for a low pitch stop fail ACAWS in Afghanistan, and that was precautionary. I've shut down no less than 6 engines in the E and H, some were precautionary and some just failed or were about to fail. So what's your point again? The low pitch stop fail issue is a known defect that's being worked at the AFMC and manufacturer level to redesign the PCU. The low pitch stops don't actually fail, it's just a sensor problem. From my time working wing safety, the legacy had the J beat in ESPs by a mile.
B. As for the ALZ issue, dunno about that one. Operator issues, I guess. I clear the ALZ just as fast in a J as I do in the E or H.
C. The "Super Hercules" thing is said mostly to irritate the legacy dudes, IMHO. Who cares.
D. The J can do no-flaps. There's a reason they don't on a regular basis...the J-30 WILL strike a tail skid if you land it zero flap. The short Js can do it just as fine as the legacy Herks, but they don't practice in the airplane because 95% of the fleet comprise the J-30 and it's just one of those USAF-isms of "if most of the fleet can't do it without risk of damage, then none of them should". It lands just like a legacy bird in zero flap configuration....and other than emergency procedures that necessitate it, why risk damaging the airplane?
E. Actually, the airplane only takes a snapshot of data every few seconds, so if your overspeed is very transitory, it may not even capture it...not any worse than a FE that notices your overspeed. Again, what's your point?
F. This is the part that is most controversial...and having gone from E/H to J and back to H again, I can say with 100% honesty that I'd rather have the J flight deck. You have lots of SA from all the displays and only a few people talking on intercomm. It's actually much more chaotic on a legacy flight deck on a low level and I'm always having to tell someone to "standby" so I can catch a radio call...plus if I lose SA, I have to have a conversation with someone in order to regain it, versus in the J I can just pull up a display and figure it out. The legacy intercom system sucks, I have to listen to the copilot breathing into his hot mic and the nav talking over the radio calls...you get my point.
For what it's worth, I love both the legacy and the J...both great airplanes. But the J is a very good improvement. You can't speak to that if you've never flown one.
