If you are talking about the Omega Weapon from Final Fantasy VIII then I would say that Ruby is harder for a number of reasons, first of all Ruby Weapon is much more resistant to physical and magic attacks and there's really no easy way to beat it without cheap materia arrangements and other tricks. Omega has a lot more HP (I think) but you can use a number of items on yourself to make yourself invincible and it is very easy to manipulate limit breaks to get Squall's lionheart over and over. So in my opinion Ruby Weapon is harder.
It can be if you don't know what to do, omega is technically harder then ruby but for omega you can use all your party members against him while on ruby you only can use one unless you do the revive trick.
Ruby weapon, all though omega has more hp ruby takes out your party members making you have to do it solo. But if you know the trick to reviving them then that won't happen. All though i voted for ruby Omega would be more of a challenge.
Yes because it has moves that can kill your character in one hit: Terra break and Light pillar not only that but its fast and you never know when its gonna attack and what its gonna do.
Omega weapon is only in Dirge of cerberus.
Omega weapon is the strongest of all the weapon monsters I believe.
the omega weapon ( the final upgrade for all of lightning's weapons )
Yeah especially if it uses terra break!
Yes especially if it uses Terra Break.
Omega Weapon is not featured in every Final Fantasy game. It is only featured in the Dawn of Souls version and 20th Anniversary edition of FFI, also in V, VI, VIII, XI and XIII. It is featured in the spinoffs Dirge of Cerberus -Final Fantasy VII- and X-2
Emerald Weapon is the hardest boss you can battle in Final Fantasy 7, so therefore Emerald Weapon is superior to Omega Weapon. Omega weapon is pretty pathetic in the original releases of Final Fantasy X, with only roughly 100,000 HP while Emerald Weapon has 1 million HP. Even in the European release of FFX, Omega Weapon still only has 1 million HP while Emerald Weapon has Aire Tam Storm, which is really mean as it does more damage when you have more materia, which can really be an insane attack. Also, 1 million HP.

Out of these three Ruby weapon is definitely the hardest. Emerald weapon is fairly difficult but is susceptible to the "Lucky Sevens" status which can take away about half of his HP right off the bat. If "Lucky Sevens" is attempted on Ruby weapon it will hit for 0 damage every time. Also Ruby weapon is much more resistant to physical and magic attacks. Omega weapon is probably the easiest since you can abuse the items "Holy War" and "Hero" to make yourself invincible or Rinoa's combine ability "Invincible Moon" to also make yourself invincible.

Exploring The Whole Place Should do the job.
