I have both cameras. The biggest thing you need to be aware of with both is that there are almost no SD cards available now that work in these cameras, so figuring out that problem should be the first item on your list otherwise you'll be wasting your money. There are several long threads on this forums about the problem; right now it looks like there is still one SanDisk SD card that works (only a 512 GB model, around US $200) and several people have reported success with some cards from Sony. You will need to read through the threads to learn more, especially this one:
viewtopic.php?f=2&t=91479Once you know you can find (and afford!) media, then you need to decide which camera. I prefer the Micro Cinema Camera for several reasons (not the 60fps, which I rarely use):
1) full-size HDMI port. The original BMPCC has a micro HDMI port that is pretty fragile and if it breaks the whole camera is lost with it.
2) image quality: it's not exactly the same sensor as the BMPCC and has a faster readout time, and the images I get always seem a bit richer and deeper, more "painterly" than what I get with the BMPCC. Could just be my imagination but I hear it from others as well.
But you really do need a remote, and it's a shame that the One Little Remote is no longer being made. There are lots of others, some of which appear to still be available, but you'll quickly discover that trying to fiddle with those ridiculously small buttons in the field to set white balance, shutter angle, frame rate, etc. will drive you crazy. A remote solves that problem.
I use an Atomos Shinobi on my Micro, which is a lightweight monitor that can run for hours on one battery.
Check out Dmitry Shijan's battery plate, which I just bought and is excellent, along with his other accessories for the BMMCC:
