Here's a few of the best all arounders...
-V Strom: Figure out a way to get along with the windshield buffeting and for anyone who's not too short of inseam this one's the best all arounder on the market right now, especially when you factor in the Fun Factor and the DL's small (yet still there) offroad ability. It's an amazing amount of Bike Competency, for the money.
-Naked SV (not the new S model), either 650 or 1000: There's nothing (onroad) one can't do on these bikes, once a simple $50 windshield is installed. It isn't quite as versatile as the V-Strom due to less wind protection, a less comfortable seating position (for most people) and far less passenger accomodations.
Plus, there's the hard bag issue, for those who care.
Regardless, it's right there, even moreso for those who wish to emphasize Sport over Tour. The overlooked key to either SV's (or the DL's) effectiveness as an all arounder is one common trait they all share: Eerily smooth motors at freeway cruising speeds.
-VFR: Obviously. Quite a bit more expensive and not quite as comfortable as the V-Strom for either the rider or passenger, and definitely lacking any off road ability whatsoever. Also, its relative lack of grunt loses points to the DL, but for many it more than makes up for these things with its superior sporting prowess, superior build quality and basic all around excellence.
The owner of a VFR can pretty much expect a couple hundred thousand trouble free miles out of his bike. Not so, with the DL or either SV, all of which employ v twin motors of comparitively shaky longevity.
How much does that aspect matter to you?
Too bad though about the addition of that accursed V-TEC, in lieu of the old gear driven cams. Sure wish they'd put it back to where it was, and punch it out to a proper Sport Touring 1000 ccs, while dropping maybe 30-50 lbs.
At that point there'd be little reason to buy anything else.
-FZ1: Pretty good all arounder, though better as a sport bike than as a tourer due to its relative lack of wind protection and buzzy as ***** motor. Other than on a dyno and on a spec sheet it really offers no true advantage over the V-Strom in real world sport riding, where the DL feels punchier and handles every bit as well, if not even better, most of the time.
However, if you spend great amounts of time at well over 120 mph than there's your relevant advantage of the FZ1 over the DL.
-Aprilia Tuono and Futura: Assuming, of course, you can get past the cost, Italian Bike/Small Dealer Network Ownership Hassles, poor resale value (especially the Futura), horrific drive lash, motor heat which bakes the rider on warm days (Futura), floppy mirrors, etc, ad nauseum....
Other than those issues, and considering the really good points of both bikes, well, sure, why not?
