Here is an article from Anandtech that covers what I really like to see, but I think they could have done a little more -
https://www.anandtech.com/show/12072/best-motherboards
Reviewers get to handle dozens of models of whatever (in this case motherboard). Given that whole range of experience, they can typically say "Hey, the sweet spot is X, and its what I would use if I were recommending a board to a friend". That kind of article and advise is really the most valuable to me, presuming I trust the reviewer / site.
Note, I think the Anandtech article could be done better. For example:
I think it would be more valuable to most people to have a High End category instead of money is no object. In the linked article, is the Aorus Xtreme really the best board above $250, or does it just have the most stuff thrown in? Is there, say, a $450 board that essentially covers what the Xtreme does but shaves $250 off the price?
I would prefer to see two (maaaayyyybbe 3) recommendations at the sweet spot, but not from the same manufacturer. That way if I happen to hate, say, Asus boards for example, I can get a recommendation at the sweet spot for another brand. Additionally, I really want the sweet spot to just be the sweet spot - Anandtech seems to have some unmentioned price bracket for this recommendation. If the sweet spot really is $300, then its $300 - Given the rule that I'm recommending this to a friend, I'm going to have him spend the extra 75-90 on "the sweet spot" motherboard than save a few bucks just to hit a price bracket. If I have to when making a full build recommendation, I'll cut back on Ram, SSD, or even video card as those are dramatically easier to change a year or two down the line than a motherboard (or power supply or CPU).
At the value end, I would like a little more explanation on exactly what I'm compromising on - feel free to cut / paste out of the mother board review.
If FPS review had a few of these "best" articles, the build recommendations would come together really easily. I would say, go for "Best Motherboard, Best Power Supply, Best SSD, Best Case + Heatsink (those two seem to go together a lot - ex, I need a case that will fit a D15, or a case that will fit a 360mm rad)". IMO the rest of the decisions are pretty easy - Video cards are all approximately the same regardless of manufacturer, processors mostly choose themselves for a particular budget / use case, and ram generally boils down to "Capacity + Speed + latency + RGB or no RGB".
