How important is a dedicated laptop compartment for airplane travel?

I’ve been looking at a bunch of backpacks for an upcoming 3-day trip. I’ve overwhelmed myself with research as usual but I have it down to just a few. For the moment, the Aer Travel Pack 3 and Peak Design Travel Backpack 30 are at the top of the list. The Aer has more pockets and options but it a little smaller in terms of liters and is sort of heavy. The PD doesn’t have a dedicated laptop pocket from what I understand.

Any experience with either and advice? I do tend to take out my laptop when I sit and not sure about going through security . Not sure if I’ll miss the extra pockets and stuff that the Aer has. Worried about the weight of the Aer but maybe not a big deal for airplane travel?
