Similar designs... major differences? DD Frontline and Claytor Expedition?

Visually, the Claytor Expedition and DD Frontline hammocks look pretty similar. I'm sure there are differences, but I don't know what they are. Can anyone here enlighten me? With shipping from the UK, the DD is a few bucks cheaper than the Claytor so the price is close either way. I'm not asking which to buy, just what the differences are (so I can decide what to buy. Ok, so I'm masking that question that everybody asks.)

Thanks all.
