Noob question about url structure

Hi guys, I know that might be a stupid question but I want your opinion:
Let's say that I want to rank for keyword "Best gadgets"
If my URL is: site.com/best-gadgets-guide is it ok?
or should be site.com/best-gadgets

Does it make any difference? Thanks!

It's totally fine. Make sure to be relevant as much as possible and always have any word of your kw in the permalink. Search on google for "play free games" and check Arkadium's structure of the ranked page. Relevance is the key nowadays.

@onlinework thank you very much for your answer!
