You can't really beat Absolute for the frequency of reloads and unlike most sites, they don't count the bonuses against your rake. But there really isn't much harm in trying some other sites and seeing what you like (there are certainly bonuses that will clear faster than Absolutes'). Though if you're doing well where you are I wouldn't stop playing at Absolute while you explore a little (it can cost a little to get used to new interfaces and new players and their playing styles).
