All suspension designs all aim to achieve the greatest pedaling efficiency whilst providing the best dampening of ground irregularities.
In an ideal world you want to enjoy the ride up as well as the ride down. Meaning you want your bike to pedal well uphill and be stable and smooth downhill.
Sadly, you can only have either of these qualities as designs are a trade off between dampening and pedaling efficiency.
When a bicycle pedals well up, it is usually light, nimble and has short suspension travel. A downhill bike on the contrary will be plush, have long travel and be heavy.
The mission profile of a bicycle will therefore determine which characteristics a suspension will have:
Will it need to react to all bumps at the cost of efficiency ? Will it need to be light or accomodate a bottle holder ?
Is it blockable ? Can you adjust its travel ?
These trade offs in suspension designs will generally be reflected in the kinematics of the suspension.
Single pivot are known to perform well downhill (e.g Specialized FSR). Virtual pivots like dw-link (Dave Weagle) are known for their pedaling efficiency.
It is not all black and white either: There are some virtual pivot on downhill bikes, and single pivot XCs.
It is all a matter of balancing the characteristics you want your bike to have.
Weight also comes into play or course, with more linkage weighing more.
To address your question directly the difference between the two designs you show are mainly a matter of personal taste and preference for a particular 'feel'. Both bikes seem to be light enduro bikes, with roughly the same program. You can expect similar handling characteristics and only getting on the bike will allow you to tell which one you prefer and how well it suits your mission profile: Do you like climbing more than bombing downhill ? If so pick the lighter bike with the best pedaling efficiency and maybe a rear suspension that you can block.
