<human>: Give me a shortened version of the text

I opened my first Roth IRA in 2015 and contributed $5,500 to FFFHX with fidelity. I am currently about to make my 2016 contribution and am considering either FDEWX or VFFVX. 

Most of the people here seem to prefer vanguard accounts due to low costs, but I'm torn in this case. 

FDEWX has no transaction fees and the net expense ratio is .16%. Morningstar only gives this fund 2 stars. 

VFFVX has a $75 transaction fee to buy (I would only buy once as I am contributing the full $5,500 at once) and the expense ratio is .18%. Morningstar gives this fund 4 stars. 

I am currently 25 years old and have 6% going into my 401(k) which is allocated into Principal Lifetime 2055 separate account.
<bot>: which fund is the best choice for my Roth IRA (FDEWX or VFFVX)? Is the $75 transaction fee worth it to do the vanguard account? How much weight should I give Morningstar ratings?
