Ive been useing glass from day 1. IMO i like it beacuse it “should” be perfectly flat, remov9ng any concerns over a warped buildplate.
That being said if im in doubt i use hairspray and double check my layer height.
The one problem with a glass bed is if your bed loses its heat (say a power outage) you can lose the print as it can easily become unstuck due to the contraction as it cools.
Ive used the creality glass bed to great success and recently installed a plain surfaced glass plate. Both work like a charm with pla, the plain glass sheet leaves a smooth finish which i think looks awesome.
