I've used every type brass available in the 204 except for Norma. I do have a 20pc box of Norma I bought just to see if they were better than Nosler.
Can't see anything in the Norma that would lead me to believe they're worth the extra cash over Nosler. Haven't shot them yet though.
Even the high priced stuff can be a crap shoot depending on how fussy you are.
Of course the more you spend the less likely you'll get junk. Both Nosler and Norma are pre prepped and weight sorted. Both offer plenty of quality though overpriced in my opinion.
I've heard complaints of Nosler being trimmed to short. Mine weren't.
Hornady has never given me reasons to dislike them. I've shot more Hornady than anything else combined. I'm shooting Nosler now though.
Rem and Win can really seriously let you down at times. I have 600pcs of Win that are completely useless. I have 200pcs of Rem in 223 that are just as bad so I figure that could happen in 204 also.
I also have batches of Win and Rem in 204 that are quite serviceable.
The answer to your question is Norma or Nosler followed by Hornady.
For Win and Rem I would suggest buying a bag of each. Compare them side by side and rush to buy more from whichever lot you prefer if any. Easier said than done I'm afraid
Learning proper annealing techniques helps in the long run. With the long freebore in factory 204's consistent neck tension plays a big role. JMO
