What I would choose and why:
I would choose the TCL 40 SE. While the Oppo A15 has the advantage of being lighter and having a Corning Gorilla Glass 3 screen, the TCL 40 SE offers a significantly better overall experience. The combination of a newer Android version, a faster chipset, more RAM, a brighter and larger display, a higher-resolution camera, a larger battery with faster charging, and stereo speakers makes it a far more capable and enjoyable device for everyday use. While the lack of specific screen protection on the TCL 40 SE is a concern, the advantages in other areas outweigh this for me. The slightly larger size and weight are acceptable trade-offs for the improved performance and features.
