The problem with the single-port router-on-a-stick is that it effectively cuts your throughput in half. 10/100/1000 is full-duplex, but since your traffic is going both ways on the same port you get 1G total rather than 1G in each direction. Having two gbe ports means you can get a full gigabit in _both_ directions at once. Not sure how often that would happen in the real world, but for some it may be worth considering... The other question is whether the hardware can do that kind of throughput... I've run for years on an old crusty J1900 with 3 realtek NICs onboard, and while it can saturate a 1G connection with bulk traffic, it does struggle to route small packets.
