I originally wanted banks... ordered it and then two weeks later called to see where it was. It was backordered, so I cancelled and went with S&B and haven't looked back. Definitely a performance difference from stock.

I like the iBanks and will probably get a derringer (preferably from a local retailer), but I don't think I'll give them any more money beyond that. After seeing how their exhausts turn out and having to deal with their crap customer service when my gauge shipped without the OBDII cable, I barely trust them. They definitely lack follow-thru. I'll be picking up an S&B once I'm in TX.

I also had to call Banks a week later to find out why my cold-air intake had not arrived. Ordered it with my DPF-back exhaust, which arrived in only a few days. Called Banks and got the village idiot on the phone after being transferred several times ... his unprofessional response was “you will probably see the intake in a couple weeks”. I agree ... poor customer service experience after the purchase.

One other thing I did want to mention ... the Banks intake does have a trick design feature where the filter itself moves independent of the air box housing connection ... instead of using those accordion-style rubber boots. Not relaying this justifies any price difference ... just glad to see them thinking outside the historical designs.

I'm sure close to an aftermarket box in performance.
The opening to the fender is very small on stock box, the opening to the hood is fine.
I opened the fender hole as much as possible.

Performance increase may also depend on filter size and type. The banks filter is huge, much more surface area than stock. So if the truck is air restricted due to the stock size or type of the filter, then just opening up the stock air box on the bottom may not make any difference. It may require a different type of filter.
Notice, I said "may" throughout. Unless a modified stock airbox alone is tested in the same manner as Banks or S&B, no one really knows. But I wouldn't hesitate to open up the side or bottom of the stock box either way.

Unless you are running a 500+ hp tune your factory air box will provide plenty of air for what your truck needs. The gains from an aftermarket intake will be virtually none performance wise under 500 hp. But To answer your question i prefer the banks. I have seen and held both and went with banks.
