Congrats and welcome to the forums! While the signup bonus was better when I got the SkyMiles Platinum and DW got the SkyMiles Gold, I actually have a bit of remorse in not signing us both up for the Reserve since the time for those companion certificates would be coming around and it would have been nice to get four r/t domestic first tickets for the price of two. Almost positive we'll both be upgrading.
Would you mind sharing any stats you care to divulge and the starting line?

Why didn't you go for the Delta Platinum? that card also has an annual certificate and only $195 annual fee.
I don't want to speak for OP, but without the Amex Platinum charge card, the difference in AF gets you Delta Sky Club access and a better Miles Boost and MQM bonus for spend. Also, as I mentioned, I have a bit of app remorse since Platinum only gets a Main Cabin companion ticket, whereas the Reserve gets Main Cabin, Comfort+, or First Class companion ticket. The latter can easily justify the AF difference, although it does stink that many of the routes I'd want to use that on have DeltaOne cabins instead of First Class.

Got it...not worth the AF for our type of flying. We're currently happy with our AMEX Platinum and Delta Platinum

The only thing I don't like about the companion certificate limitation is that the redemption must be in the lower 48 states. Because if they allowed travel to Hawaii with the certificate it would be a no-brainer for me. Even then I might think about it at least with getting the biz version so they're not reporting on my credit report.
We plan on using it for transcon flights (as in BOS/PVD/MHT to SFO/OAK/SJC, SEA, LAX) that take as long as flights to Europe so at least in this one case our value of the certificate might be a bit different. If your SkyMiles mailing address is in HI, AK, PR, or USVI, you get a much better value since those residents do get to fly to and from the CONUS. Not really fair to the rest of us since two Hawaiian residents could fly HNL-EWR in First Class for only about $2300 total!!! Then again, we're relatively safe from lava and would it really be fair to only allow inter-island travel?
