Perspective: this difference is one hour of US fintech engineer time a month. If you have to self-build a single thing on Hetzner you get as "built-in" on AWS, are you ahead?
If this is your price range, and you're spending time thinking about how to save that $400/month (three Starbucks a day) instead of drive revenue or deliver client joy, you likely shouldn't be on AWS in the first place.
AWS is for when you need the most battle tested business continuity through automations driving distributed resilience, or if you have external requirements for security built into all infra, identity and access controls built into all infra at all layers, compliance and governance controls across all infra at all layers, interop with others using AWS (private links, direct connects, sure, but also permission-based data sharing instead of data movement, etc.). If your plans have those in your future, you should start on AWS and learn as you grow so you never have a "digital transformation" in your future.
Whether you're building a SaaS for others or a platform for yourself, “Enterprise” means more than just SSO tax and a call us button. There can be real requirements that you are not going to be able to meet reasonably without AWS's foundational building blocks that have this built in at the lego brick level. Combine that with "cost of delay" to your product and "opportunity cost" for your engineering (devs, SREs, users spending time doing undifferentiated heavy lifting) and those lego blocks can quickly turn out less expensive. Any blog comparing pricing not mentioning these things means someone didn't align their infra with their business model and engineering patterns.
Put another way, think of the enterprise column in the longest pricing grid you've ever seen – the AWS blocks have everything on the right-most column built in. If you don't want those, don't pick that column. Google and Azure are in the Team column second from right. Digital Ocean, CloudFlare, the Pro column third from right. Various Heroku-likes in the Getting Started column at the left, and SuperMicro and Hetzner in the Self-Host column, as in, you're buying or leasing the hardware either way, it's just whose smart hands you're using. ALL of these have their place, with the Getting Started and Pro columns serving most folks on HN, Team best for most SMB, and Enterprise best for actual enterprise but also Pro and Team that need to serve enterprise or intend to grow to that.
Note that if you don't yet need an enterprise column on your own pricing grid, K8s on whoever is a great way to Get Started and go Pro yourself while learning things needed for continuous delivery and system resilience engineering. Those same patterns then can be shifted onto on the Team and Enterprise column offerings from the big three (Google, Azure, AWS).
Here's my TL;DR blog post distilling all this:
If YAGNI, don't choose it.
