For me, my favourite skin type is where they get more and more clothed/armored the more you unlock from them. Skins like Drift are an archetype for this. It also doesn't have to be like 5-6 layers for me.
My least favourite skin type is where they not only just give the clothes a different colour scheme but then also just slap a random helmet on them that doesn't really fit their outfit style. With the example of Miles Cross I would've preferred a bit armour over just a helmet.
Also, I do know you can just not use the helmet which I do in several cases if the skin looks good enough on its own.
