I've looked a lot, I do my best to maintain an open mind in regards to color. Where it's made with how it's made is my primary concern.
Just one metric looking for the heaviest duty 8' blade (non-hydraulic for this just because that's a lot of variable weight):
RB1584 rear blade weight 284#
Brushhog 100 series 84" rear blade weight 836# (lightest 8' blade was 572#)
Dirt Dog 70 series 84" rear blade weight 572#
Rhino 70 series 8' rear blade 572#
EA 84" rear blade 645#
Even if it's weaker steel but more of it to equal a better steel from Land Pride (which is doubtful) double the weight does a lot more work for you. Again, that's a single data point and not enough to make a decision on in my mind.
