For me, safety, on-time-performance (punctuality) and aviailability of direct flight routes rank higher than service, food and frills like in-flight entertainment.
That said, I find the service on many East Asian airlines superior to SQ, whose flight attendants tend to pander to AMDK. SQ's food has also deteriorated in the wake of COVID cost-cutting measures. The Chinese airlines (Air China, China Southern) are now in the top league in terms of aircraft age and maintenance, leg room, and food quality.
