Boy does that question always open up a can of worms! A lot depends on how many boards and what size you do per year. It is the best by far - just floats off the board during soaking for less than a minute with good toner transer. The stuff seems darn expensive at about $1.70 per 8X10 sheet shipped. Actual cost is $13.80/pack of 10 sheets from DigiKey, then add a couple or $3 for shipping you'll have close to $1.70/sheet.
That single sheet can be used 4 (or more) times. I also cut the paper to sise of my board: 3"X4" board, I just a paper just larger. After the toner transfer and paper floats off, I hang paper up to dry and reuse. I've used at least 4 times, and once 5 times.
Used in this manner a $17 shipped back of 10 sheets can last well over a yr - depending on how many boards you make a week or month.
I've got some Staples Presentation paper that does a good job with toner transfer, but more hassle to remove from copper. Not bad, but just a bit more. I don't have a number here, but it was purchased 3 or 4 months ago.
have fun ;)
