Motorola Moto E 15 vs Moto G31

Our Verdict: Same maker, different budgets: the Moto G31 is the cheaper option and the Moto E 15 the premium one. The 31 leads on camera hardware with a 50MP main sensor to the 15's 32MP, plus a 13MP selfie camera against 8MP, and the 15 has the bigger screen at 6.7" against 6.4", while the 31 has the sharper one at 411 PPI. The 31 goes up to 128GB of storage, where the 15 tops out at 64GB, and the 31 uses an OLED panel, which gives it richer contrast than the 15's LCD. Get the 15 if those extras are worth it to you; otherwise the 31 covers the basics for less.

If you'd rather pay up front, the 31 is the cheaper buy at £67 SIM-free.
