I need to break this kind of thing down to make sure I understand.
This article is a comparison of 4 B550 boards costing around $100ish, yet you seem to have gone with option 5 out of 4 here. You know, a board that isn't mentioned because it isn't a B550, was originally at least double the average cost of these boards (which isn't an issue if you already have one), and is "mature and stable" (3+ years old).
I have to give you props for creativity, but when it comes to those of us that don't have a baller AM4 board (or any AM4 board) and are vaguely interested in throwing a box together on the cheap, recommending option 5 out of 4 legit choices might as well be saying to divide by 0.
(I have to admit however, if your option 5 out of the 4 was a real world choice here, I'd take that X370 over a B550 any day.)
