I have spent considerable time in a 458 and a TTS (moderately optioned), and honestly much prefer the TTS. Like Reginos, I think the Italia interior is filled with unnecessary protrusions and plastic parts, giving the dash, for example, a pieced together look. Ferrari is mimicking its Formula One steering wheel and i don't like it in as sensuous a car as the Italia. The TTS is certainly not perfect--a bit too utilitarian--but I do prefer it by comparison.
But now the F12 is a different matter. Fabulously luxurious and sporty, at a much higher level than any Porsche except the 918.
