I've had the stock bars, the FZ1 bars, and now the Suburban Machinery bars, so I might be able to give you a little info.
I hated the stock bars. They put my wrists at a very odd angle and were just flat uncomfortable.
I was able to pick up the Suburban bars for cheaper than MSRP from another member here. They aren't cheap new (around $150?), but they're great too and I've yet to change them out and go back to the FZ1 bars (they've been on my bike for a year now). The position is slightly lower and more forward than stock, but not as much as the FZ1 bars.
The advantage of both the FZ1 bars and the SM bars is that they both have the inserts in the ends that accept the stock FZ6 bar ends. I've got bar end mirrors now (mine's naked), but the aftermarket bar ends I've got are made for the FZ6 and screw right in as well.
Some comparison pictures:
FZ1 vs. Stock (FZ1 is flat and has less pullback)
Suburban Machinery bars (blue bike) vs. the FZ1 bars (silver bike). Note, neither of these are my bike, but these are good for comparison.
