Hi there,
My personal answer to you is I do both. But it's better if you have 2 systems running. One for the automated switch pools and one for the new coins. I believe that you are mining with GPU?
If so just divide your system, if you know how to configure a single system to divide the power to do both, it would be neat. But if you just got more than one setup, I encourage you to explore and do both.
At the moment, IMHO hashcows' got a good chance for the gpu miners in terms of highest profitable switch accuracy. - But they got a problem right now and the pool is struggling to patch things back to normal.
Also try to look for the not so new coins and look for the easiest one to mine even if the profitability % is not cloud 9, you can get more number of coins and hold them until it gets more value.
Disclaimer: Do this at your own risk, cryptocurrency has a lot of it, and this should be treated with extreme caution and only invest what you can afford to lose. E.g.: Buying mining equipment, buying coins, spending too much on coffee.
