They are all about the same distance. Whichever lot you choose to park in you are going to have to take 35 back to i10 after the game.
I usually park on the corner of Houston and Coca Cola St. in lots 1 or 2 ( or across the street from lots 1-2 for $10). After the game is out take Coca-Cola St to Commerce and then a right on Walters to 35. It's always a quick exit for me.
Or if you are really unfamiliar with the area you can just park right off of AT&T Center Parkway and then take AT&T Center Parkway right back out to 35 on the way out.
