pollymer coating

As I am now smarter then before, and wiser to my 357 and its peculiar behaviors... I am wondering on the most reviewed polymer bullets. t and b has decent prices, but how bad are they in quality?

I was thinking of extreme plated 148 DEWC  but after seeing random comments on here that plated slugs are not the most accurate i started thinking on the polymer coated. 

But the main benefits that i can see for the polymer is the cleanliness in the barrel and the fact that 90% of them are bevel based for easier loading. 

The copper plated extreme look nicer is all. 

Sellier and Bellot, according to US website customer service, has stopped selling bullets as reloading components. And wont share their loading data. Lawyer issues..

dgbullets.com Dam good            Summers bullets  DG has a tripled wall box that fits inside a large USPS box ships 2000 230 grain .45 acp bullets for $18.00 bullets went up but $255 for 2000, 200 grn SWC 2250 for $262,   free shipping and 10% off for Xmas, got my last 2000 for $220

I shot 500 of the X-treme DEWC with good results at the 50' line.
And they do load easier. I use moon clips and a revolver.
Their 125 gr worked good too but didn't shoot for score.
