I use a mix. I like subdued lighting generally. The pinball life frosted ones I think are great for general GI, the non frosted ones I like for inserts. Cointakers I find I like better on indirect inserts, buttons, and accenting GI.
If you can afford it, I'd suggest a mixture of both. Get a few dozen of each and try them out. That's how I was taught to do LEDs and I do it every time. It's a very personal taste I find, and both types do different things.
