honestly both seem very similar, but the coleman has an integrated ground sheet which can help with leakage etc.
As the price is very similar I'd go Coleman due to well known brand.
However you don't say what you need to use it for?
Is it for big family holiday? How many people (with blow up beds do you need to fit in? From my experience (we have 9 man for 4 of us as bedrooms only just fit double blow up bed, although do state for 3 people each room, we use third room for storage), tents always say can fit more people than is actually comfortable.
Colemans also seem to have better reviews for bad weather and wind.
