It's €10 for the SIM card delivered (no credit) vs. 20 Swiss Francs (€17.34 today) for the Koko SIM (no credit). Some of the screenshots of the DrimSim app show a top-up option of €10 which is nice.

One thing that's not clear is the phone numbers included with each. I think it's a UK Isle of Mann # for the DrimSim. GadgetKen, maybe you can answer what number came with your Koko SIM?

My phone number comes in the format +44 7937 XXXXX which should be Jersey Telekom. So it's Jersey not IoM. At the end, it will not differ much, as the numbers are higher priced then common UK mobile numbers. My VoIP provider local phone charges 13.9 Euro cent to call this number.

See my initial post in the new Koko Mobile thread, most of the NAKA brands offer several other mobile numbers from different countries. The German number issued to me comes in the format +49 1577 xxxx.
