I love both movies, own copies, and watch them both 3 or 4 times a year. I don't compare them, they are apples and oranges, even though they cover the same material. I also don't worry about historical inacurracies in Hollyweird movies, they are just for entertainment, not historical instruction. I do get upset when History Channel or TLC productions have historic gafs, because they are representing themselves as historically accurate.
If you want to see a real good Wyatt Earp movie, also not historically accurate, just a great western, go check out Hour of the Gun starring James Garner and Jason Robards and Robert Ryan. This is a 40 year old movie that still holds up, a reel classic.
