E-40 is more relevant in terms of current sales success probably, haven't checked the numbers but E-40 is active but in terms of Hip Hop overall Rakim and KRS-One will always be more relevant because while E-40 is a legend they are on a whole other bracket of legend and status and quality within Hip Hop. So they will always be above him, but currently he will probably make records with more commercial success.
Rakim and KRS have been musically irrelevant since about 1998.


.. Rap for my generation starts with ATCQ/Wu Tang/Nas/2 Pac
