Big pike on tip-ups is the only situation where I prefer a 10" hole. Mathematically you can fit up to a 25" girth through an 8" hole so you're not going to catch a pike that won't fit through the hole, but there are other factors at play. It's no so much fitting them through the hole as it is getting them started without catching on the bottom, the 10" makes this a lot easier.
I've seen two instances where we had esox stuck on the bottom of an 8" hole, one pike and one musky, both low 40's fish that eventually came up the hole but took some finessing. The reason it happened is due to the fish's long snoot. They were both hooked in the back corner of the mouth and their face was too long that when the fish was pulled to start it up the hole, its nose got caught on the far side of the hole and the fish just laid there. You could pull all you want, but the fish wasn't coming up the hole.
Quick strike rigs are pretty awful for getting caught on the bottom of the ice, an 8" hole only makes this worse.
When fishing tip ups, an 8" holes freezes/slushes over quicker than a 10" hole will.
Cons to the 10" are pretty obvious... Weight, more time drilling a hole, wet boots, etc.
