From my personal experience brown is easier for typing, so if you don't game then I'd say get brown. Red is great for gaming, typing on red takes a little bit of time to get used to.
As for between the 2 keyboard, my vote is Leopold FC660M.
It's cleaner also the gap between the insert/delete cluster is actually good for muscle memory. I typically don't like it when they cram too many keys next to each other.
