When you consider that 16oz of Prime treats 5000g and 16oz of most of the rest of the dechlorinators out there only treat about 960 gallons of water, I think the choice is pretty easy for those of us with large tanks or multiple tanks considering that Prime doesn't cost that much more.
Prime does smell pretty bad but it has never made my tanks stink even when overdosed.
