Hi Relax,
I think this won't be happening. Why?

If risk of funds more or less the same, it will give more or less the same return.
So now you have fixed the variables - risk and return for both funds are similar.
Then you can confidently decide that the fund with the lower charges is the winner. In this case - Fund B.
It is like a mathematical equation, let's assume that you will select a fund based on these criteria:
Fund = Return - Risk - Cost (of investment)
Fund A = ReturnA - RiskA - CostA
Fund B = ReturnB - RiskB - CostB
Now you say that RiskA = RiskB, ReturnA=ReturnB, if CostA > CostB, we should choose Fund B because it is more economical.
In your scenario, Return A > Return B, Cost A > Cost B, Risk A = Risk B, then we can really use some number and calculate whether in the long term, is Fund A going to outperform Fund B.
But if you said that the funds in same categories, same strategy, same portfolio. Therefore, Risk A = Risk B and Return A = Return B.
So just compare the cost you will get the answer straightaway.
