Active management can be justified by superior returns. Most actively managed funds are not superior performers, hence the Vanguard fanatics here. T Rowe Price has a number of actively managed funds that have consistently outperformed their respective indexes for at least a decade. Multiple decades, in a couple of cases. I own several and would not trade them for lesser performing Vanguard funds.
On most broker websites you can compare funds. I'm not sure you can do it on Yahoo Finance. I'm a Fidelity customer, and their fund comparison tool is helpful. If the fund has been around long enough, you should be able to compare the hypothetical growth of $10,000 over the last 10 years. Some of those T Rowe Price funds put their competitors, and their respective indexes, to shame. If you cannot compare the target date funds for 10 years, compare the funds of which the target date funds are comprised.
Vanguard is not a superior company in my opinion. The website is very weak. Customer service is so-so. Their actively managed funds are generally cheap but not top performers. In your shoes, if the T Rowe Price target date fund is comprised of better performing funds, I would stick with that one. If you want to hedge, put some of your future contributions in the Vanguard fund.
