TIPS Studies
If your future state pension has a COLA [like SS does], and it's going to account for a good portion of your retirement income, you do not have all that much inflation risk, so TIPS aren't that necesssary - versus someone with a non-cola'd pension.
As LOL said, the TIPS have the highest credit quality [and thus are very safe], however note that your stable value fund is not marked-to-market like the TIPS fund will is. So the stable value fund will just keep going up, and will never have a down quarter/year. However, the TIPS fund can do bad in some periods and well in others. To give you an idea, here's the Capital, Income, and Total Return for Vanguard's TIPS fund [VIPSX] vs. the stable value fund in my 401(k):
