My personal top 3:
#1: Funyuns (and not the new Steakhouse Onion flavored Funyuns which are not good).
#2: Doritos (Nacho Cheese flavored)
#3 Grippo's BBQ Potato Chips (Ohio, Indiana, Kentucky) These are by far the best barbecue potato chips sold in America imo.
Herrs Crisy & Tasty Chips. 
I am from Cincinnati. The only way Grippo's is the best is if you've never had anything else. They're Ok (different), at best(jmo). That said, my favorite pizza joint, I posted about, has a "Big Grip" pizza that's topped with crushed Grippo's. I'll report back.
My favorite is Utz/Mike Sells Too/Real Hot. I love all Doritos, that I know of.
The Fritos with French onion dip.
For Doritos, I like the cool ranch or taco flavors.
Falcon Ridge GC in Mesquite,Nv. makes the best fresh tater chips ever!
Late July are the best corn chips, and nobody else comes into their time zone.
A lot depends on how you use the chips other than just stuffing your face right out of the bag. I like Frito chili cheese chips crushed up in a bowl of chili. Tostitos Scoops for building nachos. For just eating chips with a sammich a good kettle chip is good. I like restaurants that deep fry their own chips to serve with a sammich.
Extra Toasty Cheez-its are a go to.
Krunchers jalapeno
Fritos chili cheese
Lays bbq
"Quite Possibly The World's Best Potato Chip!"
Walmart had a jalapeno cheese doritos equivalent that was very good. Discontinued. I haven't found anything close.
Best Potato Chip - any decent brand of "kettle cooked" - starting with the original Cape Cod. I especially like the "low-fat" variety. LMAO A low-fat kettle-cooked potato chip? Okay
Best Corn Chip - a no-brainer, Frito's large-size, gauge Dip Size. Yeah, you can scoop up a nice hunk of whatever dip!
Cape Cod potato chips. Hardly ever eats corn chips. Probably Fritos.
