Well Im not sure it's established which one gives the most strength. Anadrol will build more muscles than dbol which would mean after the cycle you're stronger with anadrol. During the cycle however dbol will fill you with a ton of water which by itself will help with strength. That's one reason why anavar being a quite a bad muscle builder still can yield more strength than what would be expected by it.
You can't run M1T very long, liver damage is often exaggerated but not with M1T. So now you'd have to consider that in to the equation too. If you can run something longer it's gonna build more because of that.
Halo and chequedrops are unique to this equation being such dry compounds and yet add strength. I can't really say wether they are better for that then say M1T or anadrol but they are strong, halotestin (can) hold water, cheque drops shouldn't.
To me it's obvious to pick anadrol or M1T ahead of these two because they are safer, they do make you stronger long term for sure, short term? I can't say.
Cheque drops would have to be dosed from micrograms up to around 5mg to be potent enough to add size and at that dosage it would still be weak in terms of size.
If you go by (strength gain) mg/mg i would guess and this is just me guessing that halotestin would be the strongest
