Question [Q] [Poll] Dalvik or ART?

I saw in few custom KitKat ROM-s for GT-I9300 have runtime chooser. I personally use CM11 nightlies, and I tried both, Dalvik and ART. IMPO ART seems like bit smoother but there are some apps which are unsupported just yet (PES2012 i.e and many others), so I decided to ask community: What kind of virtual machine runtime you are using? Please share your opinion about each.
My Devices:

SAMSUNG Galaxy SIII GT-I9300 Int | TWRP | CM11 ROM
Blueberry NetCat M-12 | CWM | Custom kernel | Custom 4.2.2 ROM
