The 750d sits right next to the 70D as it uses much of the same hardware. You won't be disappointed as the camera is very capable and stacks up well against more expensive dslrs.
Everything because canon quality; As I have used canon cameras for many years because they're the most reliable and you have a lot more choice when it comes to lenses; Also there's a built in canon lens data base so you can get the best from your shot as the camera corrects the lens.
There's nothing to dislike.
