Simplified thoughts on K-5 II vs K-5 IIs ?

I've read here and elsewhere many things about the K-5 II vs K-5 IIs.  It's confusing!!

I want to upgrade from the K-7 to one of the above due to their reported high ISO performance, less noise, better dynamic range, better AF.  www.dxomark.com has been helpful here.

I shoot landscapes, sunsets, macro, events and family portraits.  i keep post processing to a minimum (am still getting a handle on it).  I don't envisage enlargements beyond 16 x 20.  I'm looking to put myself out there in a more proffessional way - especially family portraits and selling landscape prints/images in the near future.

Lenses used:  FA 50 1.4, FA 100 macro 2.8, Tamron 28-70 2.8, Sigma 70-200 2.8, Tamron 17-35 2.8-4.

Does anyone have any simplified thoughts on the pros and cons of either body and/or recommendations?
