Yeah, Ultor is probably better than Deimos in many aspects. The variety of buffs, which you pointed out, does make him better than Deimos, but I don't think that surviving better is pure RNG, as you put it, due to Deimos' higher HP.

As to Ultor surviving Void Causalty, Glorious, or Grand Hazard, those are all very good points. However, he can only do it once. Yeah, it will allow you to save an angel idol, but after tanking the first Void Causalty or other ultimate, Ultor won't be able to do it again unless you put the Angel Idol on him. Of course, Deimos can't do it at all without outside help.

Personally, I don't think more damage is really needed. Ultor can give the highest ATK buff, but if I recall correctly, spark and crit buffs (which Ultor does have on his SBB) do more for overall damage than an ATK buff. The crit damage buff is also negligible with Reis and Griff coming out. That's also not mentioning the fact that there is crit-resistant content.

Overall, Ultor has many good points that make him a better sub than Deimos (his buffs and ES), but Deimos' tankiness with his sphere and ES shouldn't be taken out of consideration either.
