A microswiss hot end is great, and gives you the ability to print in much higher temperature material than what you can print with on a standard FF extruder. (standard FF has an internal PTFE liner in the extruder, and it degrades above 230)
However, depending on what you print, and how, an all metal hot end can also drive you crazy because it can introduce issues you may have never had before.
So, I always recommend doing the all metal hot end swap after you are VERY experienced, and then only on 1 extruder until you get good with it.
I have had clogs with Microswiss and PLA, that I just can’t resolve. I however print PET and Nylon which would not be doable on my standard FF extruder. So I have all metal on one and standard on the other extruder.
