there are few types of custom rom, but basically there are 2 major types:

- custom rom based on stock - this will have all the features of stock rom, most probably minus the bloatwares

- aosp rom and their 'kang' versions - this will give you pure android like nexus line, so no touchwiz, sense, zoe, etc
