When purchasing my DE from RazorEmporium, I had also purchased a beginner's blade set that included a handful of offerings from each brand:
Lord
Astra Blue
Super Max
Dorco
Treet
I should note, on my first shave I had used Treet, which RazorEmporium designates 2.5 stars in terms of sharpness (Astra Blue is 2 stars in sharpness for comparison) and I cut my face up with it. Now that could have been due to the blade or due to inexperience. Been using Astras since.
There are a few okay blades available from Lord, Super Max, and Dorco. (my opinion of course)
Lord - Platinum Class
Super Max - Diamond anything
Dorco - Prime and Titan.
That said, it's truly a disservice to new shavers to specify the "sharpness" of a blade. It makes no sense. Shavers of all levels need to know that "mild" blades can feel rough depending on the face, and facilitate "over-shaving". This is one of the main reasons I tell people to keep trying new blades until it clicks, and it feels SMOOOOTH. The sharpest blade in the world could also happen to be the smoothest blade for your face. Less passes = less chance for irritation. "sharper" blade, assuming it's compatible with your face = less passes (hopefully).
Every noob owes it to themselves to try:
Feather
Gillette Platinum
Gillette Nacet
Gillette 7 O'Clock Yellow
Gillette Silver Blue
