Nothing against a good knotted leader, but the step-downs are abrupt, and the knots can and do collect weed and slime.

Hmmm...not quite. A furled leader has distinct steps as anyone who has made one will readily understand. They do not have a smooth taper in the same way that an extruded tapered leader does. In this sense, a furled leader is much more like a knotted leader. Typically, they have 5 sections but can be made with as many or as few sections as one wants. (Granted, there are no knots to catch weed.)
As for shock absorption, that again depends on how they're made. The reason why some furled leaders provide a lot of shock absorption is because they have a weak or loose furl. I would hazard to estimate that commercially available furled leaders are only furled with a 10-15% compression factor, i.e. the final furled leader is 85-90% of the length of the strand runs pre twisting/furling. That's a very loose furl - the theoretical maximum tightness is equivalent to a furl reduction of 37%. What a loose furl means is that when the leader is tensioned, it can extend (shock absorption) but this comes with twist. The same thing happens during casting (albeit less so). So twist can be an issue. The other thing about a loose furl is that it can easily be damaged.
I furl to about a 25% compression factor. This makes for a hugely tighter furl, more robustness to the leader (if you have ever had to break off a snag with a furled leader that is loosely constructed you'll know you can end up with a twisted mess), less twist (with less shock absorption but more "feel") and better energy transfer (turnover). (A 37% compression would mean an infinitely rigid leader which is, of course, undesirable.)
I would say that an extruded tapered leader should have many advantages over a furled leader. The taper can be smooth (as opposed to stepped as in a furled leader or knotted leader) and there is also the opportunity to change the composition of the base material from butt to tip end so as, for example, to have a stiffer butt end and softer tippet. None of this is possible with a furled leader.
That said, I had fun making my furled leaders and greatly improving on the techniques used in order to achieve a tighter furl and better leader. If you look after them, a furled leader can last for quite some time (as would an extruded leader if you used tippet rings.) I make them with thread, copolymer tippet material (much preferred for dry fly fishing) and fluorocarbon (especially for saltwater). I can change the taper, butt thickness etc to suit each weight of line I use.
