Seimen's Artis 2 S VC

I have worn ITE anologs for 11 years. It is time to change. Does anyone have experience with either the Seimen’s Artis S VC or the Siemen’t Cielo 2? These are the 2 that have been recommended by the audiologist. Is there that much difference ($300) per aid in the two. It is just more bells and whistles? Bot of these are BTE. I am interested in how others have got along with the BTE.

Thanks for any input
