Right, and then there is the "discard" factor when using SSDs. The SSD works better when knowing which data blocks are used and which are unused; writing with dd will set everything as "used" (this will not happen with mkfs + cp). If you want to use dd to copy filesystems, it would be wise to also use e2fsck with the "discard" option to rebuild the used/unused map of the SSD after the copy. Same thing with swap (I would hope mkswap implements discard), if you copy the entire disk.
