If we do try to look on the current situation of the entire market bitcoin and all altcoins in the market is low which means or we can presume that profit is less. Difficulty+ Electricity cost = Less Profits and also this would depend on how many miners you can able to operate.For me i would go on GPU or Altcoin mining, it might be low but would really give you the chance to mine various coins depending into their profitability unlike on bitcoin which difficulty would be always a problem and you cant get out into another options.
