FACS (fluorescence-activated cell sorting) and MACS (magnetic-activated cell sorting) are two types of cell sorting techniques. Each method has its own advantages and disadvantages. 

FACS has several advantages over MACS:

• It is more versatile and allows for more in-depth isolations, allowing researchers to separate cells based on their size, granularity, and surface markers. 
• It can measure a larger number of parameters on the same sample.
• It collects information from millions of cells in a few seconds.
• It yields higher purity.
