When describing a situation or outcome that was positive or advantageous, there are various synonyms to express that "were favorable". Some alternative options include terms like "successful", "promising", "beneficial", "fruitful", "encouraging", and "prosperous". Each of these words conveys a slightly different shade of meaning, but all imply a positive result. Other options include "auspicious", "fortuitous", "optimistic", or "advantageous". Depending on the context, one may be more appropriate than another, but all imply that the outcome was desirable and beneficial in some way.
