Rk-9000V2 for sure. Here's a few things to consider:
1. Costar build, Costar stabilizer (no mushy bottom out vs the Strafe).
2. The angle plug is to reduce strain on the mini B port, for durability reasons. You can always buy your own cable later if you don't like it.
3. Standard bottom row, good if you switch keycap later.
4. This is preference, but I like the minimalist look better.
5. This might or might not be an issue, sometimes complex USB implementation has issue on KVM (if your work uses it) and Rosewill will not have that issue, Strafe you have to flip to BIOS mode so it uses 125 Hz (default is 1000 Hz).
Another similar option is CM Storm XT (full size) or CM Storm QuickFire Rapid (tenkeyless).
