It really comes down to the complimentary upgrades to the First Class. We know it is even difficult for a Diamond member to get a free upgrade. Gold status is pretty much meaningless.
I recently used the Global Upgrade Certificates to upgrade my flights from Seattle to Taipei. The round trip economy ticket cost $823. I bought 2 so the total cost was $1,646.
A Delta One ticket was selling for $4,500 on the same flights.
I called Delta and was able to upgrade both tickets to Delta One. Total savings: $9,000 - $1,646 = $7,354.
