There is no right or wrong. But, if you are smoking for affect, then puffing clouds of smoke are probably what you are looking for, and that is not to be criticized, perfectly ok.
But, if you want the most flavor and the most absorption of nicotine, then smoking slow is the better way. Smoking slowly, rolling the smoke around my tongue, playing with it in my mouth, frolicking even, relishing every nuance of flavor is what I enjoy the most. Just puffing smoke in and out isn't giving me anything except a nervous habit... for me. You may have your own reasons.
But, I have noticed that when I smoke slowly, my pipes all seem to cake more evenly and faster, which means I have to clean more often, but it could be a sign that my pipes like being smoked this way. I intake more nicotine, making me more relaxed and languid in my seat.
I have rarely ever had a whole bowl last less than 45 minutes also. And, I am a ribbon cut fan. I would feel sort of cheated if a smoke went any faster. Quick is just not a term I associate with pipe smoking.
By the way, I tamp early when lighting my pipe, and maybe one more time near the bottom, but I don't make tamping a big part of keeping the bowl lit, unless I just packed to loosely. It's interesting how different people use the tamp differently. It's interesting that some would tamp to keep a bowl lit. Pipes are just interesting altogether. :
