You have a number of index funds from Great West. Check the expense ratio on those. Some of the American Funds have decent performance. As long as you are getting the class A shares without paying the load, a couple of those might be worth looking at. Often the load is waived in these plans. I have owned both of the Oakmark choices, but as the original I not version II. Equity Income (the original) performed well during the 2008 crash. I would look at those as well if they hold the same things as the original versions.
With marginal 401k offerings, I pick the best performing, least expensive funds. I make up the remaining asset allocation in my other accounts. No point in buying a garbage fund with a high expense ratio and poor performance just to have your 401k allocation match your overall asset allocation.
