I can imagine not using all their types (e.g., keeping track of virus counters in another fashion) in competitive play (due to space & time concerns), but for casual play (especially at a home where you're more likely to have room to spread out) I'm always going to use them because I find a lot of tactile satisfaction in having physical objects to manipulate.
More importantly, though, I think having an immediately tangible way to deal with the non-card permanent elements is very helpful for new players; remembering to manipulate dice can be difficult, or just not be a helpful way to immerse a new player. Experienced CCG players will probably not be as likely to benefit from this when learning, but those who are used to board games may feel a bit disconnected, and have a harder time understanding their opponent's board state. (It's harder to immediately see, for example, credits represented on dice, whereas a pile of the things is pretty obvious.*)
Additionally: I am adverse to using dice to keep track of numbers in games (in competitive play, anyhow); they are usually not very quick to manipulate, and are easy to have accidents or "accidents" with. I think paper records of player credits are fine, while recurring credits and other credits on cards perhaps should be tokens. I was actually somewhat surprised by the fact that the current floor rules do not address these issues. They do mention that players are responsible for bringing their own tokens, but that doesn't mean tokens are required or preferred or what other methods are acceptable for keeping track of various game states.
* If I want to to be more detailed in what I'm trying to get at here, the Heideggerian concepts of readiness-to-hand & presence-at-hand are what I am using to describe this to myself. Experienced players will often take that sort of abstract representation and interact with it in a way that does not require very much conscious attention, but new players have not become immersed in the game at all yet (the chits aren't even really "ready-to-hand"), much less at the level where further abstractions are natural. Obviously, persons differ in their ability to absorb the spaces defined by games as they are learning (such as being quick studies or having a lot of other experience to make analogies with), but even experienced players sometimes overestimate their ability to deal with concepts outside of physical reality. I've played Legend of the Five Rings for a number of years, but I realized that (despite what other experienced players often do), I needed a token in a particular place to represent one binary state for my board so I could immediately visualize whether it was a 0 or 1.
(I am sick and stuck in a hotel room, which is going to be my excuse for the length of this reply.)
