Cirrus Perspective is the better avionics package (12" screens, SVT, EVS).
12" screens are down to preference. I like the smaller screens and less bulky feel of the Columbia.
SVT and EVS are nice to haves and again down to preference - I personaly find the flight simuator SVT display irritating when flying pure IFR and switch it off - for me it leads to confusion what my primary nav is, and when IMC the horizon line is too faint - but would definitely have it on IFR in mountains...
The real advantage in avionics in the SR22 is that it has a dual AHRS, while the Columbia only has one. Definitive safety benefit, something again I would pay for - wouldn't pay for SVT..
Shame the Cirrus electrical system is so poor...
