I generally favor an RCE over an appeal because I might be able to resolve the case faster with an RCE as opposed to an appeal. If the appeal process were faster, I might favor an appeal, instead.
Q6: RCEs after final rejections
Between myself and fellow practitioners, I know of too many instances where an Examiner refuses entry of an after final amendment on the grounds that it will require an additional search, only to then allow the case on first action after an RCE.

The extension of time cost can become significant relative to the RCE fee, making it more likely we would more quickly file an RCE.

Forwarding to the Examiner needs to reliably take only a few days (not weeks or months).
