A cine lens generally has very consistent performance. No focus or aperture breathing, everything stays very constant as you change the parameters at which the lens is operating. This is important in video, hence the cine lens nomenclature. It is also non-trivial to make and design such a lens, so they tend to be rather expensive relative to non-cine equivalents.
I have had the Voigtlander 40/1.2 for quite a while now and it is easily my most-used lens. I often have it mounted when I grab the camera on my way out not knowing if/when I will capture something. Tons of character when you want it, yet stop it down to f4 or more and turn the focus ring to the infinity hard stop for really nice point-and-shoot-like landscapes. Still, I am admittedly a MF diehard and not a people photographer very often and understand the MF may not work well for that. If you do go MF, I highly recommend focus magnification. Either assign it to a button (what I usually use), or turn on DMF and the magnification will kick in automatically when you turn the focus ring. This makes quickly focussing pretty easy, and is much better than focus peaking in my opinion. I mostly use magnification over peaking.
If you are not stuck on 40mm, the Sigma 45mm is supposed to be pretty good, though it sometimes has issues with AF-C (AF-S is fine I guess). The Sigma 35/1.2 Art is also reputedly pretty good. And of course the Sony 35/1.8 and the 35/2.8. I had the 35/2.8 at one point - very small, very sharp, but some people find it too clinical or some other nebulous term. I know, too many choices, and I am not helping much.
What did you not like about the Batis 40mm? That might bring some additional ideas out.
