I haven't used many ramps in the area but the ramp location compared to where you are going to fish is a prime consideration for me. I believe Fenwick and Turtle Creek marinas both use the same ramps. (Not Sure but google maps shows it that way) I go in through Turtle creek Marina and pay $5? for a ramp fee. Nice ramps little to no waiting usually, parking is close if a bit rugged if the ramp is busy. It is close to the reefs for the bite early in the year.
After the spawn and the fish move to deeper water or if you want to fish the can lines or the islands, Catawba State park is good but the truck parking area is a long walk from the ramps.
My favorite ramp later in the year is Mazurik but the lines can be long and some VERY amateur drivers which can be exhasperating . I have seen large Cigarette boats launch there so water depth and ramp length are not an issue. The parking area is close and porta potties are clean as an be expected.
Mazurik has a nice boat prep area before eh ramps to allow you to do your final checks, load coolers, put in your plug and untie the boat. I always leave the crank rope attached until the boat is in the water. Prevents premature release (not a good thing) but you can get your feet wet if you do it this way. If you don't have all rollers on your trailer, someone holding the bow line will do the trick.
