I've been in El Poblado 3 months and I'm planning my move. Spent the last 4 weeks walking around Laureles and Envigado and here's my real take:

El Poblado: amenities are amazing, English everywhere, you'll never feel "in Colombia" exactly — feels like an expat island. Pricey. Loud at night.

Laureles: greener, quieter, less English, way more "actually living here" energy. Cheaper. Walking everywhere is easy. Cafés are great.

Envigado: even quieter, more family vibe, harder if you don't have a car/moto and don't speak Spanish. Cheapest of the three.

Going Laureles. Tell me I'm wrong.
