Personally, I don't give 650's much thought at all. To me, they are only an unending supply of available body parts.
LOL! That's hilarious.
I can give a quick comparo to my last TLS (98) which may shed a bit of light on this as well.
Newer sportbikes are supposed to supersede older models. In sportbike terms this means more power and better handling. The SV is deemed to be the new TL by many. So it's a failure compared to the TLS.
MY TLS had 120 rwhp. Shorter gearing, bitubo rear, Racetech front, TRE, racing airbox & filter, Hyperpro damper, full Yosh race exhaust, LSL kit, and the list goes on (a bit of engine brething as well). The bike turned telepathically fast, had a front wheel elevation control as opposed to a throttle, and was pretty comfy with the bars and Corbin I had.
On turn in and power it easily eclipsed the SV I have now (even stock, the 98 was not a neutered TL, the 99 and on were). So it was a better bike right? Bullshit. More fun, yes, for short bursts. BUT you had to be full on mentally wired and were usually reversing the throttle just to keep a lid on things when you weren't going for it.
In a turn, one quarter of a millimeter of throttle in first sent the front end soaring skyward. Not much fun when you are just tooling around and not wanting to devote every synaptic response to focusing on total bike control as if you were racing Rossi out of the final corner. The ride was a bit punishing after 30 minutes (even stock, much worse after the mods), and with the handlebar mod there was no shield configuration that would not buffet you, unlike the SV with the stock shield and bars.
So the SV was doomed in the minds of the sportbiking youth, it wasn't the latest, greatest, fastest new bike out there.
But I think it's a far BETTER machine as evolved.
As much fun as a TLS going for a rip? No chance!
More fun after an hour, going for a longer trip, living with it every single day for every type of riding? Absolutely!
And the engine even in DL1000 guise still doesn't bore the ever loving crap out of me like the Honda Superhawk did. The SV1000S is a winner in every respect.
