The superstar nano are good if you can find them in stock.
I've tried saints*, nano but have ended up with RaceFace Chester flats. Grip and feel are absolutely fantastic, they are a plastic composite but don't let that put you off. The others got battered when I've hit rocks, these still look perfect and they alway clean up like new. The bearings are replaceable but again, are like new.
* had lots of bearing issues with these on 3 bikes, forever dismantling and adjusting!
