A question regarding AV1 encoding in 2 pass and CRF (self.av1)

Which one do you prefer? Any reasons why?

I though it would be possible to mash CRF into 2 pass, but apparently it's not how it works. I knew I couldn't do it with HEVC and h.264 but I though that AV1 processes video differently.

So, are there any bitrate savings using one mode or another while achieving the same quality or are they the same?

Whether 2-pass has benefits for the "constant quality" mode in AV1 encoding, depends entirely on the encoder. For aomenc, you want to always use 2-pass for slow offline encoding, as otherwise important features are disabled.
