I think 505 is my favorite. Although it is getting hard to find locally. I use June Taylor, too. I find that some cans work better than others. And, it seems to not work as well if the can is colder than room temperature.
505 lasts awhile for me, too.
The Sullivan's holds very well and for quite awhile, but the smell is awful! It comes out like a fogger, spraying everywhere, and the smell just lingers. I wouldn't use this inside unless you have several doors and windows open.
