Really depends on your priorities. The Ti has more 'stuff' and the ride is a bit smoother, and of course there's no tiger under the hood...it's more of a kitty cat.
I got rid of a loaded Ti for an ST1 and I have ZERO regrets...but I prefer more engaging, 'angry' cars to luxo-mobiles. I wouldn't mind re-skinning the seats with that good looking Ti leather, but other than that I'm thrilled with the car. I don't miss the MFT at all, nor the DCT.
