I have done both and prefer the VIP seating. If you plan to really see alot of matches over many days, you will want the most "kiester-friendly" seating that you can get. (Sam's Town does have comfortable general seating, though, compared to the other places I've been).
The other thing is that you can feel good about supporting the tour. They need it. Unless you can travel as much as Gremlin, you probably can only get to a couple of events a year, at best. I will pinch my pennies elsewhere the other 50 weeks a year and be tableside in Tunica and Peoria.
