Pipe Dope vs. Teflon Tape

What is the pros and cons of *dope* vs. tape. I recall somewhere where it was stated that tape acts more as a *lubricant* so that when the next time you unscrew the pipe, the tape acts acts as a lube.

Dunno bout you pros but I tend to use Hercules Block for gas fittings/pipes and Real Tuff for Water Supply. When doing the fittings on the gas coming out of the wall....I use Real Tuff as well since it cleans easier than Block.

Love to hear what you guys use - reasons, pros/cons of different products, etc.

I use "regular" Oatey pipe dope on water and gas. The reasons are these. It's very quick and easy to apply without worrying about going the right direction or being too heavy. It is also very effective and that's why we use anything. Joints don't leak. Oh yeah, I went through a period of using tape. The white kind for water and air, the yellow for gas, but such a hassel to get it wound on the right direction, not too heavy but not too light. It did work, but dope is quicker. The only drawback, if you wish to consider this a drawback, is dope can be messy.
