Glass can compensate for build plate irregularities.

I don't have to put glass in the freezer. PLA will come off almost instantly as will PETG. Having multiple glass plates means I can pull a print still on the glass and add a new glass and ready to go in a minute. This is especially good for ABS where I don't want to force the cooling. I can set the print aside and let it cool slowly to avoid warping or cracking.
I also have glass plates with PEI on them for problem prints.
It gives me options. This is what works and I know how it performs so I use it.
Spot on reply. I have 3 beds. I only use the freezer for parts that get really stuck. It is nice when you can slap another bed on while a part cools. I almost always print with ABS. The glass just moves the entire process outside the printer while giving a nice finish.
