Current King of non-BT or EM-CCD Cameras?

I'm leaning toward purchasing the Hamamatsu Orca-AG for my new lab
next year (actually, two of them). We use Quantix Retiga 1300R in my
current lab, and the QE of the Orca appears to be a lot higher over
the entire visible range, especially out to 650 nm (where I would like
to use Alexa 647 more). So, I'm comparing the Orca mainly to the
QImaging (Exi, SRV at this price range?) and Photometrics CoolSnap
HQ^2. Image quality and sensitivity are the most important factors
here, but speed is also a consideration, as they will be used for
intensive time-lapse experiments. I would appreciate any "testimony".
Thanks.
