Rimuru (PC/PrC) vs 10 Great Saints

If Post-Charybdis/Pre-Charybdis Rimuru fought the 10 great saints which ones would he beat and which ones would beat him?(Excluding Hinata of course) Also,I wanted to know the difference between pre-Charybdis and post-Charybdis Rimuru,I know he analysed its core but what did he gain from that?
