The A52, A52 5G, and A52s 5G are three different models. They share many specifications, but main differences are in the CPU and display. If you look closely at the specifications, you will see the differences. But essentially, if you rank them by specs, it's A52s 5G better than A52 5G better than A52.
I'm on the A52s 5G and it's an okay device. Some stutters sometimes, and the camera is oversaturated, but the display is very smooth and has good battery life. It's good value for the price maybe. Between the three, you should probably get the A52s 5G, as it has the best specs.
