What is the most efficient way to make UI circles?

I know of 2 ways to do this. I just wonder what is the most efficient way?

Code 1:

local parent = script.Parent
local color = Color3.fromRGB(0,0,0)-- makes the frame a Color3 RGB value
for i=1,360,1 do
    local frame = Instance.new("Frame",parent)--Makes a frame
    frame.Rotation=i -- Sets the rotation
    frame.Size = UDim2.new(0.5,0,0.5,0)--Sets size
    frame.BorderSizePixel=0 --Remove the border
end

Setup 2: Use a decal
