GSAM best groups?

GS has gone through multiple reorganizations and was hoping someone could provide some color as to which groups are now the best within GSAM. The MSI group within SSG used to be highly respected. Does this group still exist / does GS have a top tier special sits group anymore? Which groups within GSAM are now considered the best? How are the corporate PE and Hybrid capita groups in NY? And finally how do the top GSAM groups compare with GS IBD classics for someone coming straight out of undergrad who ultimately wants to work at MF PE or SM HF? Thanks!
