I used the Gold Medal Models PE set for my 1/720 Enterprise build and everything fit quite well.
My only beef was the inclusion of the older 4-bladed props for the Hawkeyes; I'm hoping Lauren Perry will include the newer 8-bladed ones in his next update of this fret. I had to buy two sets of White Ensign Models 1/700 airplane bits to get enough 4-bladed prop pieces to make the 8-bladed ones for my Hawkeyes!
