As good as the Leica M Monochrom?

The other evening I was watching a B & H Photography lecture on YouTube led by Michael Ernest Sweet. He mentioned that the Ricoh GR (I'm unsure which version) had an in camera black and white setting that was on par with the monochrome images produced by the Leica M Monochrom.

I have heard good things about its in-built black and white but had never really taken the opportunity to test it out on mine. Over the last few days I thought I'd shoot solely in JPEG with the camera effect set to black and white. 

I have done absolutely no editing to the following images, simply uploaded them here, straight out of the camera. All of them were taken with a mixture of aperture priority or shutter priority.

Naturally the contrast could do with pumping up somewhat - far too much grey tones. That said, overall, I think they look pretty great.
