I think it depends on how you use your pack. If I am just transporting gear to a site, then the big bag pack works OK. But if I am working out of the pack, then the "tactical" packs are a better choice for me.

Having the ability to configure the pack for the activities expected is a big advantage. Some days I want my PLB where I can easily access it, some days it stays home.

I don't have to dig through a big pack to find something. I can open a small pocket, get what I need and return it when done. This reduces the risk of dropping something un-noticed or having rain or dust coat everything.

My Maxpedition pack is over 15 years old. It leads a hard life. Last week it spent 4 hours in the back of a pick-up, along with assorted hardware like Hi-lift jacks, winch cable, shovels etc, as it bounced down a desert road. Several of the light weight packs developed chafe holes. Mine still looks like new.

Having gear in multiple pockets also reduces loss from cut & run theives. They may cut a pocket, but my pack will not do a gear dump on the street. Also, wearing it in front as is customary in the third world, or US urban areas, means I can get something out of a pocket without exposing all my contents to onlookers.

Guess it depends on how you use your gear.
