I think it comes down to quality, and what to expect from each morph.
There are calicos that look like sugars, and vice versa. However, if you know what to look for, you can avoid getting fooled by folks who want to change names based on the market which confuses the community and muddies the market with now poor quality versions of the morph you're trying to buy.
For sugars, they tend to have thick black backs with blushing. They should have wide empty alien heads along the side of the body, and typically a good amount of white. I find their coloration to be less intensely orange than good Calicos, and will be more brown. Here are some examples of what I believe are quality Sugars and Sugar combos:

And Calicos don't necessarily have black-backs. They can have normal patterns, but a good Calico is closer to orange than brown. Typically a Calico will also have a banded pattern, not so much a black-back, fat alien head pattern like Sugars. I've seen MORE low-white Calicos than low-white Sugars, but they can both produce a variable amount of white (similar to how pieds produce low and high whites).

I went with Calico simply because I found one I liked for what my plans were for. Here's my Calico as a baby:
