It is always hard to say what is more profitable, at any given time, as two main factors have to be considered:

1. The price of cryptocurrency you are mining (the higher the better for you as a mine),

2. The costs of mining: electricity + the actual tools to mine (miner gear).

So 1st factor has to be as high as possible and 2nd factor has to be as low as posible, then you will have insane amounts of profits....
But as we all know, those two factors fluctuate time to time.
