After reading all 4 pages, what are the parameters...? It can't be price, or "custom" vs. "stock"...to determine a tier. I've seen Luke Skywalker competition race guns with a Tiffany, Cartier list of mega bling components FAIL...
and a cheap utterly neglected and abused Taurus always work..
So, I'll use a performance car analogy,
Stock Ferrari: "Top Tier"
Stock Aston Martin "Top Tier"
Custom 69 Camaro with a "package" to run 9's in the 1/4 mile and remain street legal...."top tier"?
Seen a tweaked up Mustang come close also.......

Certainly a Mustang/Camaro can't compare to an Aston Martin in the stock fit and finish category,.....but,....with a little tweaks and love....it would leave them behind.
So the Les Baer, Ed Brown, "custom's" tweak an otherwise "stock" pistol and give it tweaks and love to make it top tier.
While a $500 Glock (and some others), out of the box, are damn hard to get to fail, even with cheap a** steel case dug up surplus.
Great ideological question, certainly manufacturers, over the years, got "some" models right, and "some " models wrong.
I don't think that necessarily changes a "tier" rating.....
Plus there is caliber considerations....and that is another "tier" in the mix,....
