These are my recommendations as a HOBBY baker that does NOT sell cakes. I purchased the hexagon set of Wilton pans with a 50% off coupon from Michaels. They work beautifully. However, either set would work well. Note that the sets from Wilton and FD's are different sizes.
Here's a photo of a 15" x 2" high hexagon cake made with the Wilton hexagon pan:
The Wilton Hexagon set is $50 before coupons and has the following sizes:
