I like the crushed cheerleader lube but it really doesn't do a whole lot for chains.
I've never used Bioshield but I have used Chain L and I like it but only on bikes where I know it could get rained on a lot so I use it my touring and MTB chains. For my regular road bikes I use ProLink Extreme, it keeps the chain looking cleaner and the lube lasts a long time if you follow the directions to the letter...which is the same with Chain L, you must follow the directions to the letter. I also like Rock & Roll Gold, the Rock & Roll was rated for having the least amount of friction of any of the bottle lubes Chain L was rated in the middle but the ProLink (though the test didn't say which ProLink was tested) was rated for having higher friction so the next time I buy lube I want to try the Rock & Roll Gold just to see and try it out.
