In case it wasn't obvious enough from the photos, the "Respect Mode" is basically where the middle part of the upper booster pack retracts as an homage to the missile/booster pods on G1 Jetfire (and the Macross VF-1S Super Valkyrie). The "Gerwalk" mode isn't technically part of that mode; it's just something that the toy can do because Skyfire does have that mode in the cartoon. The mask is also an obvious homage to G1 Jetfire's original face, minus the antennae.

I think the thing that makes the starboard corner hard to tab is getting the slots to line up perfectly. Something which Siege Jetfire doesn't have an issue with because his booster pack doesn't contract/expand during transformation. I understand that it's done to make the backpack look narrower like in the cartoon model, but the trade-off is that you have to get the slots to align perfectly with the tabs. Still, given that the backpack has to contract for cartoon likeness' sake, I do like how they worked in that "Macross booster" homage into it.

The articulated fingers looks amazing, but compromises on grip. I prefer how Siege Jetfire has that retractable 5mm slot, whereas Skyfire just holds his rifle like most other MPs and BTs; via palm slots for tabs on the gun handles, which lends itself to a rather loose/weak grip.
