Canon 600D (4500 yuan), Nikon D3200 (4500 yuan), Nikon D3100 (3400 yuan), how to choose? Mainly for shooting still life in distance, for online store use

If you want to shoot people, buy a Canon 600D, and if you want to shoot scenes, buy a Nikon D3200, D3100 or D5100. Now the D5100 only costs 4,500 yuan. I recommend you choose between the 600D and the D5100. I struggled and compared for a long time, and finally bought the D5100. Personally, I think the D5100 looks better and smaller than the 600D, not to mention the performance. However, most people use 600D for shooting in online stores. I mainly take photos when traveling.
