If you can afford the micro color panel and asking which editor keyboard to get, I will say the full-sized DVR keyboard. However, my concern with keyboards that are customize to just a specific app is what happens when down the road new and better software capabilities (or you decide to use another NLE) are available that the keys don't support. Hence I don't usually invest in custom keyboards because they are over priced for one thing.
The Speed Editor is nice because it can augment your standard PC keyboard. There are even keyboards with key labels for Resolve on them that cost around $130.

That totals to around $425, about 40% of the full-sized DVR Editor keyboard.
For me, my hopes is that BMD will come out with a speed color panel that's around $295 and will complement with the speed editor. If they do that, then I will invest in both. Otherwise, unless I'm doing some massive editing and color grading and getting paid for it, I will continue to just use a standard keyboard and trackball mouse solution, and the contour Shuttle. I also use the Tangent Element app ($11) on an Android tablet for color grading. That works just fine too. My 2 cents.
