I've done both types of RP, and honestly I've both had success/failure for both. Pre-planned skips the whole "Does the character like mine?" or "Is the player themselves even interested in romance RP." However to me it takes most of the fun out of it.
Either way, success or failure comes down to the individuals behind the characters, and not whether it was pre-planned or not.
