3rd Gen What is the best dragon or steel pokemon?

Flygon and Aggron aren't contenders for strongest steel or dragon.
​

It's in the OU Tier in the Advanced Generation, but is it the best? Well, let me evaluate. I say that Salamence outclasses Flygon in this tier. Both are very good dragon Pokemon, but Salamence is overall better.None of Flygon's stats are larger than Salamence's, whereas Salamence outclasses Flygon in HP, Attack, and Special Attack. This gives Salamence the upper hand in bulkiness (even though it's marginal) and both of its offenses. Salamence is extremely versatile because it is able to Attack with both offenses with great power; Flygon is quite predictable with not many options at its grasp, with most variants being of Choice Band.

Salamence hits extremely hard with a 135 (most of the time boosted) Attack stat. If it gets in 2 Dragon Dances or so, it's gonna take a lot to stop it. Flygon can't pull this off as well with a smaller attack stat and being a bit more fragile and vulnerable.Flygon may have the upper hand when it comes to weaknesses, but Salamence surely outclasses Flygon when it comes to resistances. Salamence may only have one more resistance, but it's resisted move types are much more common. Come on, it's not every day your opponent uses a Poison move on you! Salamence also gets a little more bulk with 95 HP, so that should help it live a little longer.

I'll stand by my opinion that Metagross is far superior to Aggron in terms of power and strength. There is a reason why Metagross is in OU and Aggron is in UU. I'll get us started by taking a peek at their statistics first.Whoa there, there's quite a big difference between the two. You have to admit, Aggron's special defenses just suck. It has no speed to save it from the nightmare either. Low HP, terrible special defense, and a lot of common specially-typed weaknesses aren't helping it at all. We'll get into weaknesses later. You'll notice an impressive 180 defense stat, however. But is it enough? I'm questioning it's usefulness right now. A majority of Aggron's lack of potential has to do with it's typing. Aggron, with no boosted offenses, can't hit very hard on it's own. It is easy to wall, set-up on, and stall out, giving the opponent a big opportunity to win.

Metagross, on the other hand, has an impressive 135 attack stat, with especially durable defenses (both physically and specially) too. What a great combination! A balance in offense and defense make up to a great tank Pokemon. It has an interesting movepool with Explosion, Pursuit, etc. Okay, onto weaknesses / resistances:Metagross and Aggron both have a number of resistances. However, it's the weaknessess that hinders Aggron's ability greatly. Weaknesses to some of the most common types in the metagame aren't helping Aggron at all (especially when they are x4, with one x2 weakness on the special side). Even with 180 Defense, Aggron dies easily to a harsh blow from fighting or ground type moves. Take my word for it, I've battled Aggron before and not even it's 180 Defense can take x4 hits. Needs better HP too.

Metagross has a much better typing over all. Two common weaknesses, only two, doesn't hinder it that much. At least it's not a damaging x4 weakness like Aggron. Metagross's high attack stat allows it to deal damage, while it's defense stats and the number of resistances allow it to take hits very well. It's a strong and durable tank for the OU environment.
