I like the Whisker Biscuit best for hunting, and find no disadvantage to using it for targets as well.
It's quiet, simple, durable, inexpensive, and reliable.
I thought at one point that the only drawback would be that I (assumedly) wouldn't be able to shoot flu-flu's through the WB for bird hunting or aerial targets. Finally tried it with some old flu-flu's that I had lying around, and found them to fly just fine through the WB as well!
They can be a pain in the neck to tune at times. I was used to tuning all my setups to perfection by shooting bare shafts and fletched ones, and bringing the two types together at one point of impact at thirty yards. Something about the full containment feature of the WB prevents this from happening, at least on some setups that can be tuned quite well with other rests. However, the tuning can be achieved by an alternate method of using all fletched arrows and bringing fixed blade BH's and field points together as closely as possible using the normal tools of rest movement, nock point movement, and tiller adjustment.
Before I settled in with the WB, my favorite was the NAP Flipper Rest, which shared many of the qualities of the WB: quiet, durable, inexpensive, simple, etc., but lacked the full containment that is very handy when hunting.
Lots of others work well, but I couldn't find any that worked better.
The fall-away types seem to provide some advantage to release shooters, but it's questionable whether they are suited to finger shooting. Some "experts" say they are not, but my very limited shooting with one of them was very promising. A friend who also likes to experiment and is another stubborn finger shooter converted a prong rest to dropaway and shot it with fingers throughout our winter indoor league a few years ago, but found that combination to be too tricky unless he also used a side pressure button in the bow.
To sum it up, if you're just looking for a sure-fire, "can't go wrong with this one" rest, the WB is as good as it gets.....just don't worry about bareshaft tuning with one, thune using fixed blade BHs/FPs.
Among the various models of WB, I'd recommend the drop-in ones over the old originals without the loading notch, and my next one will be one with the marks that allow you to record and regain your settings when playing with other tuning positions, and the clamp that holds the biscuit perpendicular. Mine is the standard cheapie now, without those features, but I'm convinced they would have been worth the extra cost.

A fingers shooter, particularly one shooting compound bare bow doesn't want to be trying to fool with a wisker biscuit!
