The Mako is THE straightest non-putter disc ever created. I've thrown one many times and the ratings on inboundsdiscgolf.com are accurate. This disc is straighter than most putters too. The Buzzz doesn't even compare.
That said, the Skeeter may work better for you if you are used to throwing slight hyzer for your midrange shots. If you just want a slightly faster Mako, wait a week and the Mako3 will be available.
The QMS might give the Mako a run for its money, especially in CE.
