If the T6/1300D has the features and capabilities that allow you to get the kinds of shots that you want to get, then it's good enough. Are there better cameras with better resolution and dynamic range? Of course. But the difference isn't going to be huge. In fact, you can easily produce a photo with a 1300D that significantly better image quality than a 5D Mark IV simply by using a better lens on the T6/1300D. What most people don't realize about image quality is that the lens is doing 90% of the work. A cheap body with a great lens will always have better image quality than an expensive body and a cheap lens.
Instead of looking at it in terms of image quality, choose the camera body that provides you with the features that you need. This could mean that you go with a Sony or a Pentax. Pentax, for example, is actually a significantly better camera than Nikon or Canon in the entry and middle level of cameras. Pentax has superior build quality such as being weather and dust proof. You don't get that on Canon or Nikon until you spend 2-3 times more money. Pentax is the only DSLR brand to have in-body image stabilization. This allows you to use any lens ever made for the Pentax system and still have a stabilized image up to about 5.5 stops. This feature alone will allow you to get shots that will vastly better than any Canon/Nikon because instead of being at ISO 3200 (for example), you'll be around ISO 200 to get the same shot. That is that power of having in-body image stabilization.
The Pentax also uses pixel shift for still life and landscape photography. During the shot, the camera moves the sensor 1 pixel at a time. The camera then blends the shots together to produce a sharper image with superior contrast and color that you simply cannot get from any other camera on the market today. This is because of the Bayer pattern on sensors which have many more red pixels than green ones. Moving the sensor allows Pentax to create one image with an equal number red, blue and green pixels. This and many other features are found in all Pentax DSLRs; you don't have to spend a lot to get a lot more than what Canon or Nikon can or do offer. So if you want to put your friends images to shame, then get a Pentax like the K-70.
Ultimately, it is not the camera, but what you do with it that matters. If you were to compare your friend's shots taken with a DSLR, they would not be as good as a professional using an iPhone. Your decision on subject matter, lighting, composition and exposure settings are what matter most. However, if you want better images out of the Canon system, then you will need to either sell the 18-55mm kit lens that you must buy with the 1300D, or skip the 1300D and buy a higher-end camera that comes body only so that you buy the best lens for your needs and within your budget.
