I assume you are comparing at the same scale? It is hard to discuss styling
without a screen snap or web service to reference.

Different projects describe a vastly different shape of the world and have
different distortions of scale (often as you move north south). It looks
like the two projections you describe cover the UK and and a large section
of the northern hemisphere respectfully.
