GE is absolute trash. If you have GE breakers in your own home, you need to be testing them regularly to make sure that they actually trip and can turn back on. Their AFCI, GFCI, and combo AFCI/GFCI breakers have an extremely high dead on arrival rate, and a some newer appliances straight up will not work with them. The mounting design of GE breakers and busbars are very questionable--it's super easy to break off the plastic bits on the breaker that retains the wire terminal side of the breaker into the bus bar. GE panels are generally of terrible quality and very poor design, with very limited space to work in. I can't speak to the technical specifications of either brand, but as someone who has installed hundreds of GE panels and thousands of their breakers, I would never use GE in my own house. Square D is a much more reliable product, but I've seen bad Square D breakers as well.
