Honestly, they both work fine. I think the Maple have a better bang for your buck.
But right now, I'm quite enamored of Battle Rock Studios and their really great Myrtle plinths. Cheaper than the Mapleshade and much, much better looking.
I'd be interested in any feedback you have about the Terrastone platforms. I see you've got experience with Mapleshade as well. Have you compared the Terrastone platforms with anything else?
