I use a combination of Beat Detective and manual slipping to get the right feel for the performance. Most of the time I use 70 to 90% strength with quantization, and if the feel is still somewhat wrong, or there has been a misquantize or mistrigger, I will sort it manually. Good drummers take about 1 hour per song once I'm in the swing of things, decent drummers and perhaps more technical songs about 2 hours, and bad drummers and technical songs are 3 hours+ (I'm talking when I have to absolutely reconstruct the beat because the drummer couldn't work out what he was doing).
I'm not crazy enough to do it with Cubase.
