Personally I prefer the X-T20, which I owned for a while and that 18-55 lens is excellent, definitely prefer it over the canon kit lens (which I had with a canon 80D).
If you plan to add more lenses in the near future though, the Canon lenses are normally way cheaper than their Fuji counterparts. The Fuji lenses might have better image quality, but the system as a whole lack budget options for some focal lengths.
If you don’t have any plan of adding any more lenses, either of them should be fine. It is really hard to find a bad camera nowadays really. Again, if you don’t have any plan of adding more lenses, I think X-T20 might have some advantages over the 750D, because the kit lens is better, and X-T20 has better and more tactile controls for learners. The jpegs from X-T20 might be more pleasing than those from Canon too for beginners don’t want to get too deep into post-processing yet. Some gotchas though, to get the absolutely best sharpening results from the Fuji X-Trans bodies like X-T20, Capture One or Iridient is recommended rather than Lightroom, but probably not something you should worry about yet. I have also found X-T20 got some relatively high failure rate of internal battery failure which cost a couple of hundred quid to fix. I might be paranoid, but it might be worth of having a warranty in place or sell it when the warranty runs out.
