If you were considering the XH1 instead, I'd personally go for the Sony A7III. But it's almost always out of stock since it was just released. It beats the XH1 in just about every category - except for color (in my opinion).
Note that the XT-2 is about a year old. And the discount may be because the XT-3 is on its way.
Fuji XH-1 Is Fuji's Best Mirrorless
The X-H1 is the highest performing camera in the X Series lineup, with a newly-designed robust and durable body. The X-H1 incorporates a range of useful features that support shooting in various scenarios by professional photographers, videographers and experienced amateur photographers. These features include not only the first-ever X Series camera with 5-axis in-body image stabilization, which has a maximum of 5.5 stops, but also a flicker reduction mode which enhances the quality of indoor sports photography.
