After some critical shots blurred from handshake and watching this video, https://www.youtube.com/watch?v=7lKV3SVfvFY , I have to disagree that IBIS is not the main factor of decision. Also don't forget the fact that XH1 is cheaper than the XT3 as of current pricing on shopee. I am yet to find out about the dynamic range advantage of XT3, but for me, getting a sharp focus is always more important than extracting a little more information from the shadow or the highlights. I guess to each his own.
