66toolkit and AtoZ SEO Tools use cases
For a focused SEO tools website
AtoZ SEO Tools is the stronger match if your whole positioning is around SEO utilities such as plagiarism checking, backlinks, meta tags, keyword position checks, robots.txt, sitemap generation, and domain checks.
For a broad web tools platform

For monetizing users with paid plans
66toolkit includes payment plans, recurring and one-time payments, coupons, taxes, invoices, credit notes, customers, and 19 payment gateways under its Extended License.
For running a free ad-supported tools site

What to consider before choosing
SEO depth or tool breadth
AtoZ SEO Tools is positioned around SEO tools. 66toolkit is positioned around a much broader online tools business with thousands of tools and categories.
Ads or SaaS billing
AtoZ SEO Tools is a good fit for ad-supported SEO utilities. 66toolkit adds paid plans, subscriptions, invoices, taxes, discounts, and customer payments for SaaS launches.
Simple niche site or platform
AtoZ SEO Tools can be enough for a focused SEO site. 66toolkit makes more sense when you want accounts, payments, white label, API, broad tools, and a full admin system.
Where AtoZ SEO Tools can be the better choice
AtoZ SEO Tools can be the better choice if your audience specifically wants SEO tools and you do not need thousands of general utilities. It has a long CodeCanyon history, many public reviews, an SEO-specific tool set, user management, OAuth login, SEO-friendly URLs, ads integration, and add-ons support.
Its lower listed Regular License price can also matter for a small SEO-only website. 66toolkit should not be positioned as the cheapest way to launch a narrow SEO tools site.
Where 66toolkit may not be the right choice
66toolkit may be more than you need if you only want a small SEO utilities website, do not plan to use SaaS billing, do not need thousands of tools, and want the lowest possible entry cost. It also requires you to operate, secure, and update your own PHP hosting environment.
