Direct answer
Fondant lasts longer, holds detail better, looks smoother. Buttercream tastes lighter and more natural. Pick what matters more for your occasion. Most birthdays do well in buttercream; most weddings do well with a fondant exterior and buttercream interior.
Fondant is sugar paste rolled into a flat sheet and laid over the cake. It gives you a perfectly smooth surface, holds sharp edges and detailed work like jali patterns or lace, and protects the cake from drying out for longer.
Buttercream is whipped fat and sugar piped or smoothed directly onto the cake. It tastes lighter, melts in the mouth, and pairs naturally with the sponge. It does not hold extreme detail or sharp corners. It is the right choice for cakes you want to eat rather than look at.
The shortcut: if you are choosing the cake for the photograph, lean fondant. If you are choosing the cake for the slice, lean buttercream. Most of our weddings combine the two: fondant exterior for the look, buttercream interior for the taste.
Heat matters too. In Chennai summers, a heavily detailed buttercream cake can sweat by the time it is plated. Fondant is more stable above 32°C. If the cake has to wait at a venue for two hours before being cut, that is a fondant decision.
