The M10 has a newer processor by 2 generations (The Digic6 vs Digic4 IIRC) which basically just equates to better image quality, It can achieve higher ISOs which means potentially better low light performance, it has a vastly superior auto focusing system with far more autofocus points, the LCD is higher resolution, it’s also mirrorless, which is the way everything is going, and which makes it smaller and lighter. The 1300D does have better battery life, and some small advantages like better exposure compensation and better AutoExposure and White Balance bracketing. I took a look at some sample images, and I do personally prefer the M10 images, but YMMV
