The answer is "definitely maybe" depending on several factors. I can only
tell you about the volume factor I recommend to my client caches, but
there are others like latency etc.

Acquiring digests from my caches will have my clients transfer ~300MB/day.
Your numbers *will* differ. I tell them to use digests, if they transfer
more than ~200MB/day non-digest objects, and ICP if they transfer less
than ~200 MB/day non-digest objects. As you can see, I am a little biased
towards digests, since they put less stress on my caches during rush
hours. Since almost all my clients and I all live in the same ASN (more or
less), I didn't trouble looking into latency issues.
