Yeah, the short answer is neither at their best with the Sony stack, but people do still use them. The Techart AF adapter is the popular way to go on Sony. The manual adapters generally suck (they slip, get stuck, or are just jumpy when trying for precision). The 28's a solid 28 on film and/or with an adaptation for M mount, but there are plenty of small film-era lenses, including the C/Y Distagon 28/2.8, that are better performers on stock Sonys and much easier to adapt. I've never understood the 45's reputation. It's a decently strong performer, but it's objectively well behind the ZM Planar 50/2, which is, again, easier to adapt.
Personally, I'd let it all go to someone interested in working with the set.
