Tbh though if you grab a 6B[m] CH in the corner with 50+ meter, wouldn't it be best to go for SMP regardless? The only reason I can see you not doing it if you know they will burst after you wasted that 50 meter for rapid and you really need the meter to allow you to gain advantage over your opponent in neutral after the burst.
Litchi has a variety of enders, which all do different things; catch rolls, meter oki traps, mix-up set-ups, most damage, etc. It all comes down to what you feel is best for the current situation.
Just cuz they in mah sig dunt mean i play dem bruv, u crazy :3
