I dose everthing separately but I'm not going to tell you it's better. What's better is what you think is good. It looks like the CSM+B has your Fe which is important. Your mix seems a little odd to me because it has Magnesium Sulfate but it does not have KH2PO4. They're putting in a GH boosting compound while leaving out an important macro in a macro mix. It does make it a little hard to follow the sticky. If you like premixed, I would get a mix for GH and a separate NPK mix for Macros and keep using the CSM+B. It seems like a lot of mixes but you alternate the days you use the mixes and the GH booster is just once a week.
