Least favorite (that I have used) would be the RCBS 'roll on' stuff.
I reload 9mm (among other pistol calibers) w/o any lube as I wet tumble and include Armor All Wash and Wax in my cleaning solution.
About the only bottleneck rifle case I reload is 223. One Shot (Spray), Unique (paste) and RCBS Spray-on all work just fine for my needs.
Unique would be the most economical of those I've mentioned.
At ~$5~ for what maybe a decades worth of lube for some folks, I'm not quite sure why anyone,,,,,,,,,
