You have your experience and I have mine.
I daily drive my vehicles. Even from the first time I test drove my current CTS-V, I immediately fell in love with the low end grunt. I sold my 2013 5.0 and I do not regret it, as I am not over 4,000 RPM a lot during my daily drives.
If the CTS-V is your standard then i guess 99.9% of the vehicles on the road are gutless as well. The LT4 also best the viper v10 in torque and it has the highest displacement of any production vehicle.
