Review: Covin vs. Marek

So, I was wondering how the Marek compares to the Covin, since the Marek seems to be Hyperlite's further development of the 3DS/Pulse (Chad's old board and Rusty's old boards), whereas the Covin is Chad's new creation and basically Ronix's development of at least the 3DS.

Can anybody who knows more on this and had the opportunity to demo the Marek provide a short (or, even better, a long) review?

Thanks!
