Classic Shading

[SpiderPig]

I'm going to be using a lot of low poly assets (flat shading and plain colours - only a diffuse texture which sets the colour per triangle) and I'm not sure if the PBR lighting should be used still or if I should use the classic shading?

I would try to use the PBR approach because it looks good. Your environment maps or probes are very important for this.

I thought it might look better.  Although the colours do look more washed out than in blender. Especially the greys.  I'll take a screenshot...

Okay now that I see them side by side they're not too much different.  The one in blender does look better though.  Looks more specular.  Lighting is not my strength.

I think I just need better environment maps.

Yeah, that blue tint is probably the environment map. Make sure you are setting the diffuse and specular maps. Here are a few sets you can try:
