The biggest difference between the two is size. The Spectre has a larger gate opening and overall larger feel. I use Spectres for ice climbing draws (clipping with gloves and all, and i use Moses biners (Mammut's equivalent to the Phantom) for racking on alpine draws and gear. It just depends on personal preference, but for an ultimate alpine draw i would do Mammut contact slings with Phantom biners. Hope this helps.
