It is not a hack and its speeds are above all other miners I have checked. I thank the developers for continuing this. you can write your hate messages somewhere else if you cannot propose a logical solution.
I have checked, excavator, Gminer, ethminer, t-rex miner, phoenix miner and still claymore is faster about 1 to 1.5%.

claymore more epochs is maintained as a mod and is as good. see its link:

please see this post, maybe you have the same problem with windows update like me today:
   
Windows Update KB5004237 prevent strap driver installation of CLAYMORE mining

https://bitcointalk.org/index.php?topic=5349304

Today 15/7/2021 I have noticed my miner reboots frequently. after checking the situation I have noticed that the strap drivers were unable to get installed so the watchdog reboots the miner. more investigations revealed that the driver permissions are revoked explicitly by the issuer (that is what the event manager reports when trying to install the driver)
the error during installation was "Failed to install "driver," error 1002"
further investigation revealed windows has released a security update today (KB5004237) on windows 10 which revoked the driver installation certificate.
After uninstalling this security update and rebooting the computer, the issue was resolved.
I am writing this here so that someone with proper knowledge could propose a permanent fix to this issue. It seems somehow, Microsoft is trying to prevent any software without a certificate to be installed on windows.
