well thats hard to say.. columbia completely ruined Will's image and ran his music into the ground, and obviously stifled him creatively...
i wouldnt say Will is really on Interscope.. he is now on Overbrook and doing what he wants.. interscope hasnt really done any promotion or leg work at all.. Its all Will and Overbrook who is trying to make this a successful album all interscope has done is release the record(and the fact some stores sold out, showed they didnt even do a good job of that, should of shipped more copies)
so finally my answer is overbrook is a hell of a lot better than Sony.. interscope has actually distributed the album which is okay..but hopefully they come to the party at this stage.. of course i'll take interscopes lack of promotion over sonys meddling anyday..because the music that Will makes and releases is most important
