Which one is an efficient URL Structure?

Hello, I'm asking for your opinions about the following structures.

If we have an website with the subject CARS, and we have the following pages:

Best Cars, Best Cars under 15000$, Best Sport Cars, Best Sport Cars Under 15000$

Will you go with the following structures:

For Page "Best Cars": - domain.com/best-cars

For Page "Best Cars under 15000" - domain.com/best-cars/under-15000

For Page "Best Sport Cars" - domain.com/best-cars/sport

For Page "Best Sport Cars under 15000" - domain.com/best-cars/sport/under-15000


or each page to have a simple URL like:

For Page "Best Cars Under 15000" - domain.com/best-cars-under-15000
For Page "Best Sport Cars under 15000" - domain.com/best-sport-cars-under-15000


The Website will have like 35-50 Articles/Pages. What do you think will be the best approach in terms of ranking advantage. - Or there's no difference in link juice between doing any of those structures?



Looking forward for your opinion guys and what worked for you better.

I dont think this is going to make much of a difference in itself, but I would go for simple URL. What could help though is interlining the pages among themselves, with in content links. Another thing is you can also create a general page such as domain.com/best-cars/, where you make a small snippet about each type of best car, and then from this snipet link to the page, such as domain.com/best-sport-cars-under-15000.

But there are surely different ways to do that.

I vote for the simpler URL. As I know URL should be short. If you are using wordpress, just use the category feature.
