Put over the kitchen sink, just used the 6" drop.  The ceiling mount it too small to cover the previous light hole in the drywall, so had to buy a oiled rubbed bronze ceiling medallion to cover the previous hole..  Found one for under $10 at Lowe's (didn't check Wayfair :-(  ).  It's plastic but fairly sturdy and I think it will work fine. 

Pros: Options on length of drop
Cons: may not cover a previous ceiling light hole, may need a ceiling medallion
