So how do they drive? I was looking at getting these when I was having CIS problems a while back. Do they drive as smoothly as a good CIS, without snatchiness and hiccups on the on/off throttle changes and constant throttle?

Sheldon, these babies work great with no hiccups or hesitation as I have logged about 150 miles over the weekend. The response is so much livelier than the CIS. The revs are quicker from gear to gear and the sound is just incredible. I am only running 26 degrees advance at 4k so I still have some power left on the table. I plan to advance it a bit more this weekend.
On a side note, the carbs are more thirsty than the CIS. I was averaging about 20 to 22 mpg with CIS on normal driving. The carbs are yielding about 15 to 17 on semi-spirited driving. Since I do not commute with the car, fuel economy is not a big issue with me.
As for cold starts and warm starts, I followed Steve's advice and three pumps when cold will fire her right up. On hot starts, I crank the starter and floor the pedal at the same time and she'll fire without excess cranking. Best part is I still have the hand throttle so I can set her to idle at 2k rpms for warm up and it also acts as a cruise control on the freeway. I think this is the by far the best upgrade I have done for the car so far. I can only imagine what S cams and pistons will do...
