Outside in decent light I know the shutter speed is not an issue. 1/500 is rarley an issue so I prefer to adjust the aperture and manage my DOF.
When light is an issue I use M, honestly have never use TV or needed it. Would you need Tv if you are always getting shutters of 1/1000 (most sunny days) or more at f/3.2? Just seems silly to me unless you want a specific blur effect.
Ever shot motor racing?? Try shooting Superbikes or MotoGP with a shutter speed of 500th sec..I'll tell you these bikes are so quick at 500th they will be a blur unless you focus on a slow corner..Anywhere else you will need 1000th sec plus..
