How to choose a good 401(k) investment option?
Great question and good for you for starting investments.  Are you young, like in your 20s? I would do all that you can in the ROTH.  You will not get a tax break now, but you will get one later.  Keep in mind that any company match does not go into ROTH but the IRA. I try to look at two things when judging a mutual fund:  the historic performance, and the expense fee.  When comparing two funds, if one has a 10% average return for 10 years, and a 1% fee, I feel it is better than a fund that has a 12% return for the same time period and a 3% fee.   If they are close, you can always put a little bit in each one.   An important question to ask is if you have debt.  You may want to scale back your contributions some to pay down that debt.  For me, I don't like to go below a company match to do so, but anything over and above might be better utilized to move that student, car or credit card loan to zero.  Others might disagree, so YMMV, but I have done this myself.
