I have a weird question about mathematical notation.

Which is better for integral transforms: brackets or curly braces?

For example, I have seen Laplace transforms in both ways:
$\huge{ \mathcal{L}\{ f(t)\} (s)}$ brackets
$\huge{ \mathcal{L}_t [ f(t)] (s)}$ braces

@Herp_Derp, I usually encounter the first one the most.
