Update 1/19/16: Corrected routing throughput
When Google sent another TP-LINK OnHub for retest, it also sent a brand-new ASUS SRT-AC1900 OnHub. ASUS' take on the OnHub starting shipping at the end of October, trailing the TP-LINK version to market by a few months.
The image below shows the two OnHubs side-by-side. The two look like they could nestle snugly together with their almost mirror-image styling, but their inverse curves would prevent that.
ASUS & TP-LINK OnHubs
Key differences are shown in the spec table excerpt below. One difference not noted: TP-LINK's outer shell is removable, while the ASUS's is not.
ASUS & TP-LINK OnHub differences
Port complement is the same for both OnHubs: one Gigabit Ethernet WAN; one Gigabit Ethernet LAN; and one USB 3.0. The USB port remains non-functional, as does the ZigBee (802.15.4) radio.

I learned my lesson on the TP-LINK OnHub and didn't attempt a complete disassembly of the ASUS. But I was able to get it partially disassembled fairly easily, thanks to the use of screws vs. hidden plastic locking tabs (thanks, ASUS!) Removing the bottom cover reveals the first difference: the ASUS' speaker is bottom mounted. The TP-LINK's sits on top.

Removing a few more screws allowed me to slip off the outer shell. The view below shows two different angles.

Removing the antenna ring,then a partial inner shell reveals the view below. The main assembly has a processor board (left) and RF board (right) attached to an aluminum frame, with heatsinks atop the RF cans covering pretty much all components on each board. That's the dual-band monitor radio antenna at bottom left and the ZigBee antenna above it. The Bluetooth 4.0 radio is peeking out from the rear, behind the RF board. The single tri-color LED is the small white square at the bottom of the board assembly.

The right side view shows the RF board with its heatsink. The Bluetooth antenna is mounted to the plastic frame in the right-side photo area where the heatsink fins are cut back.
