The verdict
If you are planning your first campaign, use the Transparency site first. Look at what competitors promise and which formats they use, then write your own. It shows what ran, not what worked, so do not copy blindly.
Once your campaigns are live on Google, Microsoft or Meta, connect Adzooma and see what an audit finds. The free plan means a first look costs nothing.
These tools do not substitute for each other. One cannot research competitors and the other cannot audit your account. For a small team, I would use both, in that order.

Who each is for
Choose Adzooma if…
Pick Adzooma when you already run paid campaigns and want problems caught for you. It flags wasted spend, broken conversion tracking and disapproved ads, and you can apply fixes without leaving the platform.
It suits agencies, freelancers and in-house marketers with several accounts. The free plan limits opportunities, SEO profiles and alerts, so reporting and custom alerts sit on paid plans.
Skip it if you have no active campaigns, or if one tiny budget means the findings would not be worth the time.
Choose Google Ads Transparency Center if…
Pick the "Google Ads Transparency Center" when you want a quick look at a competitor's ads on Google, or want to check an advertiser that pitched you. It is useful before you brief your own copy or plan your positioning.
It covers Google only. For other networks, use each platform's own ad library. It says nothing about spend, conversions or targeting.
It is a free public site with no plan or support, so do not rely on its layout staying the same. Skip it if you need performance data about your own campaigns.
