Spawn or not?

In my game, I have quite a few actors which continuously fall from top of the screen towards the bottom of the screen (all at different times and speeds). Should I just make these actors spawn one after another or put a bunch of actors above the screen and have them all set to fall at certain times/speeds? I'm just not sure which way is better in terms of performance?
Any help is appreciated.
Thanks!

Thanks again, and if anyone else has any other suggestions please comment.
Try this, it's some snowballs going from right to left, but all you have to do is change the direction.

When they go off the screen at the far left they are immediately moved back to the far right (recycled) - which avoids spawning and destroying.
That's kinda the weird thing with GS, you can use a certain basic road types to get where you need to, but if it does not work, there are detours that will get you to the same place and oddly enough faster. Traffic maybe? hmmmm.
I've actually experienced the same thing (actors not spawning properly) even though it hasn't happened for a while. Also not quite sure why this occurs. I'm just hoping I won't have any performance issues once tested on the device.
Thanks for your input and good luck with your project!
Thanks! You too bud!
