The LG Stylo 5

• 6.2 inch screen (no notch)
• Snapdragon 450 CPU (14nm)
• 32GB of internal storage (also has micro SD slot)
• 3GB RAM
• 1 rear camera setup
  • 13MP regular
• 5MP selfie camera
• 3500mAh battery
• 179G weight (6.31oz)

Regarding CPU performance, it's pretty much the same almost, you can check the benchmarks here: Snapdragon 450 vs Helio P35: testes e benchmarks

I'diria que o Stylo 6 é um pouco melhor porque tem uma tela ligeiramente maior, bateria maior, e o dobro do armazenamento interno (64GB em vez de 32GB). O preço é quase o mesmo mas acho que você provavelmente poderia achar o Stylo 5 mais barato desde que ele's no ano passado's modelo.
