difference between these two methods?

local part = game.Workspace:FindFirstChild("Spawn")
local Players = game:GetService("Players")
Players.PlayerAdded:Connect(function(plr)
    plr.CharacterAdded:Connect(function(chr)
        local hrp = chr:FindFirstChild("HumanoidRootPart")
        hrp:PivotTo(part.CFrame)
    end)
end)

here's the code the method is being used on

hrp:PivotTo(part.CFrame)

chr:PivotTo(part.CFrame)

my question is what's the difference between these two? which one's better to use? they both do the same thing in my testing
