I've ridden both, and owned a Tuono.
The Brutale looks t'rrific, but it's power delivery is just too soft and fluffy low own to be enjoyable - or predictable. Then rev it higher up and like Juan says, you need to cane it, and all the time you are sitting thinking, 'come on, come on... we haven't got all day...'
Whereas the Tuono can lay darkies... while exiting a tight turn... with the front wheel off the deck.
There is no comparison in my mind. However, that TNT looks a bit cool too but buddies tell me the 03/04 Speed Triple is as good as the TNT, and however you look at it, the new, 05 Speed Triple seems pretty funky.
