I was on fence for long time cause every van has them and its hard to stand out with so little cosmetic options that are in the realm of being affordable. I don't consider anything aluminess offers to be affordable...
I picked up mine just in case the wider rear end and wider wheels brought the stance too far outside the body. it did and I ended up putting them on. I dont care for the flares at all when the wheel and tire combo isn't flush with the outside of the flare. the sunk in look just doesn't do it for me at all. however when it all sits just right, its a look that's hard tom beat on these vans...for me anyway.
all that said, good luck with your decision. 4wheelonline has some great pricing on parts and most of it ships free.
