What are the advantages and disadvantages of MLAG vs Stacking?

Today we have 4 x670-g2 in stack. We thought of changing to mlag, with 2 switches in stack on each side. What are the advantages and disadvantages of the two topologies?

This question comes up from time to time. Here's a couple of similar conversations:

Hello Branco,

this is something that has been brought up many times. We just had another fellow community member who summed it up pretty well. The only thing I would add is with MLAG it makes it easier to upgrade the cores considering if one switch goes down the other switch picks up the slack. With a stack the entire stack needs to be rebooted in order to apply the image:

Hope this helps!
