FB Ads or Google Ads

I want to get leads for a client that runs a business in the US and will like to place adverts on cars. I have tried scraping but I have not found a good source for leads. I am thinking of the best approach to take should I use FB for leads or G Ads? If you also have a good source to scrape, then I can use that too. Thanks.

If you literally type this query on Youtube you will get a wealth of information

In my opinion both are great but it depends upon the what type of business, goals and the clients.

fb just for wasting money if the ads are not for a funny pages, but google are best for serious business
