had the X5105, G1M, and GSOC for the G90... while the built-in SWR sweep and tuners for the X5105 and G90 are great, the cheap hardware and buggy firmware turned me off... i also got burned with the GSOC, as it turned out to be worthless and still not supported well with firmware or documentation...
X6100 buyers are going to end up being beta testers for a goat-rope round of firmwares, where new problems are introduced with each release...
also, one of the reasons i got rid of my X5105 - which i liked- was that eventually the internal battery would have to be replaced, and it is not plug-and-play - you have to disassemble the rig to no small degree, a schema only slightly worse than Elecraft's insipid requirement for KX2 users to have to remove its internal battery for charging
the 705 is a much more capable and refined transceiver with a polished, reliable firmware and industry best documentation, including a service manual, which you will never get from Xiegu..
no thanks, i will pass on the X6100 as a new purchase but may get a used one from a disappointed buyer at a highly reduced price, if only for curiosity's sake
