If you care about a 6-7 year window, especially the most recent 6-7 year window, target date funds aren't for you. They'll underperform when the market is doing well. They'll also suffer less when the market tanks. Overall, they're a safer investment if you really do have a fixed target date and want to retire close to that date, and thus you have much less tolerance for risk. In particular, they tune for less risk the closer you get to the target date, to limit unexpected surprises.
If you're near the beginning of your career, you don't have a fixed retirement date in mind, and you're investing a substantial enough fraction of your income that you will likely retire earlier than average, then you might want to pick a standard index fund with a fixed proportion of stocks and bonds based on your tolerance for risk, and leave it that way.
