The difference between a Blocker and spoofer is, a spoofer hides your HWID of your pc, so the gaming companies cannot actually ban your real PC IDs, therefore you can continue to cheat on a new account without being PC Banned/HWID banned. The Blocker blocks the CODs Anitcheat from working, therefore all cheats are undetected, and therefore your hardware will not be banned.

The Blocker is the best spoofer for Cal of Duty Gamrs & Fivem. 

For all other supporter Games the VIP Spoofer is good.

Note:
If you are changing from one spoofer to another spoofer or blocker, but using the same Steam or Battlenet account, the chances of your account to be banned is very high. Only switch spoofers if it's an account that has not played on with another spoofer.
