Rapid Recovery vs Second Wind

By LukeZZ, in Star Wars: Edge of the Empire RPG

Rapid Recovery (Passive): When this character recovers strain after an encounter has concluded, he recovers one additional strain per rank in Rapid Recovery.
Second Wind (Incidental): Once per encounter, the character may recover an amount of strain equal to the character's ranks in Second Wind.
It seems to me that Second Wind is only better than Rapid Recovery, since it can be used during an encounter (and has no drawbacks compared to Rapid Recovery).
Am I missing something?

No, you're not missing anything, but some Talent Trees will have one and some will have the other.

They are certainly close to one another, but as you point out, it's an important distinction - does this person catch their breath during the action or afterward.
