1. yahoo62278 : 10 out of 10. Simply the best Bounty manager in Bitcoin talk Forum. He pretty much has best Signature bounty, if you want to earn bitcoin. His bounty filled up very quick, sometimes even in within 30 minutes. So you have to be fast. Always update spreadsheet on time. Great communication. You will get paid on time.
2. ColorlessK : 9 out of 10. Had couple of bounty with him, great person, Spreadsheet update on time, He will give you time at end of the bounty, if you need to change your payment address. He does only few bounty, so it might hard for you to find him in the crowd.
3. hua_hui: 9 out of 10. Really good bounty manager, he will read your pm fic the problem and also will let you know. He will always update spreadsheet on timely manner, and will always ask you to double check, if everything is fine.
4. needmoney : 8 out of 10. I had great experience with him, he has so many bounty running, but always helpful. He is kinda slow updating spreadsheet, but you will get your stakes on time. He might not reply your pm due to overloading, but he will fix the problem, so no worries.
5. aTriz : 7 out of 10. Had few bounty with him, great person but very strict. What i mean is, you have to report your bounty on time, or you might lose your stake. If you are in his bounty, don't be late. Spreadsheet update on time.
6. deadley : 7 out of 10. Had few bounty with him, Very good on updating spreadsheet on time. You will get your stakes on time.
7. Sylon : 6 out of 10. Very strict Bounty manager, my first 2 bounty with him, stakes wasn't updated, and end up getting nothing. But after that last couple of bounty, stakes updated on time, so he is getting better with time. So he turns out to be okay.
These are my experience so far. If you know any good Bounty manager, write a small review, i will add it here, so other people can read before join. cheers
