wp-o-matic vs feedwordpress

i’ve both plugins installed but can’t achieve that what I want to yet.

I want to create posts from an affiliate sponsor feed.
1 feed item must be inserted into 1 post.

so far with wp-o-matic the description is entered in the title field and the image is inserted in the content (without any link or so).

which of the 2 plugins does this best and how to achieve this and style the inserted post.
