I also got different brands with different memory but 25% for the same model
is not normal any more.

An overclocked 1060 with Hynix chips could mine ETH @ 19.5 MH/s, while the same 1060 with Samsung chips could hash @ 24.5 MH/s. That's about 25% difference. But that's the only scenario I can think of. Neoscrypt difference would be a lot smaller, and with all the other algos he'd have 5% difference at most.

What are you mining? etash, equihash or something else?

Nothing strange in it, you cannot get same speed for every GPU even if it is of same configuration.

25% difference is pretty strange actually.

The only explanation I came up with so far is that he's mining ETH and only one of his cards has Samsung memory chips.

I have 3 GTX 1060 6 gb gpu's of the same brand on one rig.
But there is one of them that mines considerably faster than the other 2, although they are all overclocked the same way...
I don't understand why there is one almost 25% faster than the other 2?

No psychics here I'm afraid, you need to tell us what you're mining. If it's Ethereum (or any other Dagger coin) then this huge 25% difference could be due to the memory timings: one of your 1060s could have Samsung chips (with tighter timings) and the other two could have Hynix chips (with looser timings). Easy to check the memory brand by running GPU-Z. If it's not Ethereum though then it won't be as easy to account for the 25% difference.

It can be because of different memory vendor and ASIC quality.
