No problem, Guz.
The gearbox of the Gladius is smoother without a doubt. I never find myself missing shifts on the Versys, mind you, but the Suzuki's just feels more refined. As far as the engine, the Versys is torqueier...there are many times when the Versys can comfortably be in 6th where the Gladius must be in 5th. With that said, the Gladius engine has a much better growl and seems to breath better at higher rpms. Their red lines are that same. Fuel mileage is the same, but the Versys has a longer range due to the larger tank (5.0 vs. 3.8).
In traffic, I much prefer the Versys with its taller vantage, torqueier engine, and the feeling that I could jump a curb if I needed a right-now exit. For short urban rides with little traffic or open twisties for about a half-hour, there's no question that the Gladius is much more fun. For longer trips (if you level the seat out a bit), the Versys takes the prize for suspension adjustability and farkle support.
Some extra information: Suzuki just released an OE "touring" seat for the Gladius that I picked up Tuesday. I haven't put it on yet, but it seems thicker and a little taller ($170). Also, SW Motech released some quick-remove brackets for the Gladius that will accept GIVI/H&B/etc. hard cases. We'll be grabbing them shortly and seeing how the GIVI e21s work on it.
IMHO, the Gladius looks will age better than the ER-6n. The Versys with supersport tires is probably 55%-45% sport/touring. The Gladius (with its excellent ss stock tires) is probably closer to 75%-25% sport tour. However, my woman and took and 2-week, 4000 mile trip in August and she toughed it out on the Gladius on the stock seat and with some Cortech soft bags (with drybags inside...the supplied covers suck). The longest day was 600 miles. She's an excellent rider and I simply could not shake her in the twisties. So it's all a matter of how bad you want it. We also have the OE flyscreen on the Gladius that that's a must for long highway jaunts.
They are both really great bikes; just really different. I wouldn't get rid of either. I just wish my wife was tall enough for the Versys so I could ride the Gladius more when we're together!
Hope that helps!
