I feel that the best thing about mining is that it doesn't matter how well the market is doing. My electricity cost for mining stay consistent month to month unless I add more GPUs and the only thing the market may affect is difficulty in my favor if others stop mining due to cost. Now if you have 100s of miners then you probably do need to focus on the highest ROI per month, but with only 4 cards it doesn't really matter much. I agree with others though in the fact that you need to figure out a plan.
1. Are you speculating on new coins.
2. Are you focusing on a couple coins to HODL.
3. Are you mining to convert directly to BTC.
etc.

I've done all of these and I don't feel any is better than the other. I all depends on your goals. It looks like you are interested in #3. If so I would recommend a combination of something like a Awesome Miner and Mining Pool Hub. Set up multiple pools on AM and mine into MPH. You can set AM to mine the most profitable of the pools you use and then use MPH to convert to BTC.
