Distinction between librtlsdr and rtl-sdr repositories

Hi, I appreciate very much to receive your comments on the distinctions between steve-m/libsrtlsdr and keenerd/rtl-sdr (forked from pinkavaj/rtl-sdr 129 commit ago and maintained). Both have very similar structure, flies, purpose but the software is not exactly same. There are something attractive for me in one of them while the other one is also good. İs it possible to create patch from one of them and apply to the other to merge two repos together?? Why I am asking is, rtl-sdr has a new agc - aggressive agc option which is useful for me but I prefer to stay on librtlsdr; is there a solution? Thanks in advance, Murat.
