What is the best static site generator?

[Glaceptra]

I decided to make a notion on the best static site generator available in the web.
What providers can you suggest me to try?
Found FLATsite.com but still don't know if you can trust them.
Do you know anything about them?
Alternatives for comparison?

With FLATsite’s remote servers, you’ll get unlimited storage, highly secured remote servers and enterprise-level firewall for all your projects.
They are affordable and as mentioned earlier Excellent Service!

Services from kvchosting.net and brixly.uk are worth trying.
They are great quality site hosting providers, with a great value, low rate for low-income person with great services and support.

I am happy with FLATsite.com solution - they are offering 1st month at $1 - this is cool!
No doubt, Static sites produce fewer HTML requests than dynamic sites with databases and significantly boosts your WordPress performance speed.
