I know this may get moved to the Skymiles forum -- I have had bad luck picking the right place to post lately

Anyway, what is the current best Amex/Delta Skymiles offer available?

I saw this website:

https://www.deltaamexcard.com/
Is that the best place to go to see what my best offer will be? Or is there something better (like getting 50K bonus miles on the Amex Gold Skymiles card or something that I saw in this thread: http://www.flyertalk.com/forum/miles...it-card.html)?

Or even the Amex Premier Gold card if there is a great offer there too?

Thanks.
