Ben Hur doesn't have the savagery but it's near unmatched in Epicness due to the practical aspects of everything. Like the Spartacus series, which equally conveys brutality, Gladiator is marred by obvious CGI. However, considering the date of release of Gladiator, and smaller budget of Spartacus, both are still impressive. We need another Roman-era series with a big budget and Coliseum violence. I haven't seen Gladiator 2 yet, but I've watched the OG at least every two years since it came to home theaters.
LOTR Trilogy did "epic" best IMO, even today, combining CGI and loads of extras, costumes, etc... bringing to life a massive fantasy world and battles like no other. There are some other epic heavy hitters too, like Kingdom of Heaven (need 4k Director's cut yesterday), Waterloo, Cleopatra, to name a few.
