I've recently changed to ATACs from SPDs. They are fine so far. They feel a bit squishy compared to spds and it took a couple of days to change clip method although there's still a lot of habit to break. ATAcs are more expensive - initially and long-term since the cleats wear out far faster. Supposedly less likely to unclip with ATAC although I rarely had issues with SPDs.
Hands should be near brakes.
