I don't know the specifics of those two funds, but this is a general answer for comparing different investment strategies in your situation.

Expense ratio

The first thing to look at is the expense ratio of each fund. If a fund were to appreciate at a long term average of 7%, but has an expense ratio of 0.5%, then your return on investment will be about 6.5%. Especially for long-term investment, favor funds with low expense ratios.

Higher risk -> higher reward

If your retirement is ~50 years away and it is likely you will not want to withdraw those funds earlier, you should favor the riskier fund. In general, the higher the risk, the higher the reward. If you can ride out the ups and downs this risk tends to pay off. A long-term investment is generally less risky than a short-term investment.

Lower reward -> lower risk

If you think you might need some of that money before retirement (e.g. to pay for college or grad school, or as a down payment on a home) you may want to choose a more conservative fund with lower volatility. That way if the market crashes between now and when you need that money, you won't be out as much as if you had invested in a higher-risk fund.

Past performance is not future performance

What I recommend you don't consider is the past performance of the fund. In general, past perfomance does not predict future performance [citation needed]. Fund managers with many different funds will of course get lucky with some of their funds and unlucky with others, and might tout their highest-performing funds as evidence of their investment prowess, even though these funds tend to regress back towards the mean [citation needed].
