Like Claude said it depends on your budget and what you're willing to spend. Most bang for your buck is searching for a used set with compression/rebound adjustments and getting them rebuilt by a pro to your weight and riding abilities. I get mine serviced by Derisi suspension and it was about 200 dollars. As far as just plain best shock around you'll hear answers ranging from Custom Axis, Elka, Ohlins, Motowoz, Exit, Fox etc... Setup is probably going to be the most noticeable difference.
