Fancy is often casual and vague at work. It may express praise, but it can also suggest needless decoration or complexity. Use sophisticated when complex, refined, or skillful is your exact meaning. This is a choice based on meaning, not a swap for every sentence.
What "fancy" doesn't tell you
"That's a fancy model you built."
Does this praise the model, or call it overbuilt? The sentence does not say. Add the feature you value when the tone could be unclear.

Sophisticated can mean complex, highly developed, refined, or made with skill. It is often positive in these workplace uses. Yet the word does not prove quality by itself, and context can still make it critical.
"That's a sophisticated model — it accounts for seasonality and price elasticity in a way our old one never did."
"Their pricing strategy is more sophisticated than it looks; it's segmenting by usage pattern, not just company size."
Both sentences name the evidence behind the praise. The details make sophisticated more useful than a broad compliment.
