Internal vs external wastegate... which is better?

In the sloooow process of turboing my 3.2 and am using a standard K27 HF and exteranal WG at .6 bar. However, looking at newer turbos/ systems, internal wastegates seems stardard. Love the external WG for 'cool' factor and sound, but is it 'old' tech? How exactly do you vary the spring rate on the external WG? Is there any advantage? Thanks
