Form 1 paper vs e-file fingerprints

When e-filing a Form 1 is there significant difference in the approval time between sending in fingerprint cards compared e-filing digital fingerprints?

I still have a couple cards so I would be dropping them off at the post office shortly after e-filing the form.

Thanks for any info.

Talking to many of my clients, there does not seem to be.

I've done both and not seen any time difference.

Thanks for the replies.
I went with the digital EFT file. I guess I'll find out myself now.

I had 2 form 1's rejected in a row over the fingerprint cards not arriving on time.
It has been EFT's since then (thru a local shop, SDS Guns) and it all goes quite smoothly.
It is also surprisingly fast to submit with E-File and EFT's and a digital passport photo.
