Don't get me wrong, the 458 is an amazing car. I think one of the reasons I am liking the H more is that I was able to spec the H exactly as I wanted it. The 458 was an opportunity on a car that buyer backed out of and a bit dull ( titanium/black) compared to my boldly speced H. I find the H sport and race mode more aggressive than the 458 and feels quicker. While I found the sound of the 458 engine to be better, I like the exhaust note better on the H, especially when downshifting. The interior environment of the H is much more current and sporty and the electronics better in my opinion. I felt equally in control with both. Brake pedal would at times fade on the 458 which other owners have reported. I have no braking issues with the H. It's hard to explain but the H is more me than the 458.
