What Hotend Are We Rocking?

I am considering building another MP3DP V4 and I have actually started printing the parts.

My point of contention with this one is what extruder I want to use. I have been using Hemera but I am considering going with a BIQU H2 V2S Lite. Does anyone have strong opinions on one over the other? Does the BIQU have a 12V variation?
