Not in disagreement, but just to augment with a couple of other points:

The treatment time listed for the liquid is much lower, or at least last I looked. I think the tablets have a four hour treatment time; liquid is as low as 15 minutes, though typically one increases doseage and if possible treatment time for what are perceived to be sketchier water sources.

The liquid is also a lot cheaper, again, last time I looked anyway.

I've been a happy user of the liquid for many years and miles. I did get something like giardia once, but I wasn't treating at all from springs on that trail so that might well have not been the fault of Aqua Mira.
