In terms of Mobility, X has the advantage here. His movement is fast, he can double jump, air-dash, double air-dash in some series with leg upgrade, hovering, (In Blade Armor), deal damage to enemy during air-dash, dash jump, wall jump, (No wall in this arena, but he can...) Kick jump right off the wall, which, I think he can do that using the Bamboo.

Keep in mind that he is fully capable of attacking while he's jumping, dashing, etc. His fast movements will not reduce his abilities to attack.

As I have mentioned in my previous post, with U-Buster equipped, X can shoot fully charged shot everytime, or use his charged Z-Saber. The power of charged Z-Saber is not to be underestimated, for it destroys most enemies in one hit. Of course, Cloud could block it, but it may give such an impact which will break his blocking and give X another chance to attack.

His charged shot will leave an energy field (which stays for a few seconds) and it will deal damage to the enemies. This would restrict Cloud's movement. X can even take the defensive stance, keeping a distance from Cloud and just shoot Charged Buster at Cloud. (It consumes no energy)

When Cloud gets near, X can either pull out his Z-Saber, or double jump/Air-dash away. (I forgot to mention, X is semi-invulnerable in his Air-dash. Like...he only takes damage when he's close to landing, which should be far away.)

What if X gets hit? From the previous battle, I've mentioned his D-Barrier. X will be invulnerable for the next few seconds after he gets hit. It is not possible to land multiple hits to X. By equipping the D-Barrier part, the length of his invulnerable period doubles. So, keep that in mind.

I haven't even taken the charged Maverick weapons into account yet. Most of the maverick weapons are deadly when charged, (whole screen attack, such as meteor shower, acid rain, etc) the downside is that they consume energy. With blade armor however, the energy consumptions are just 1/3. X has 1 W-Tank which complete refills every single weapon X has. (8 in total) All of the charged Maverick weapons will deal damage to the opponent. (they may not do full damage every time, but moderate damage is unavoidable)

About the weather condition, I don't see how it will effect X. Well, X has fought under water, and it hardly has any effect on his performance. (Except the fact the he could jump and dash even further...)

P.S. One more thing, I don't think you can block energy shoot. Charged Shot are pure (Or mainly) energy.
