Who is better: Mega Garchomp or Mega Charizard X?

I need a Physical Sweeper, I have experimented with Mega Charizard before and I do know that:

Power Punch does massive damage due to Tough Claws and helps you start sweepingFlame Charge does massive damage due to STAB and Tough claws and helps you start sweeping

Pros and Cons are strongly suggestedalsoTake note that these Pokemon are for Competitive battles

Garchomp pros:

Amazing attack statSand boostedAccess to Swords DanceGood dual STABsCan run Fire blast for steelsGood bulk

Cons:

Sub-Par speedNo dragon Dance

Garchomp is an excellent wallbreaker, but can only truly sweep under sticky web.

Mega charizard Pros:

good bulk for an offensive monGood dual STABsAccess to RoostAccess to Dragon DanceCan run mixed

Cons:

SR WEAKNESScan be stopped by bulky waters

as a sweeperunless you have sticky web I would go for charizard

Alright, lets start off with Garchomp

ProsVery high Atk(at base stat of 170!)Either Decent or Good in all of stats

ConsSlower when Mega EvolvedHas a 4x weakness to ice type, meaning it will most likely NOT survive an ice type attackHas a horrible abitiliy, Sand Force, which it needs to set up sandstorm to activate and wastes 1 turn

If you are planning to use Garchomp, use this example:

GarchompAdamant

Outrage-Gonna sweep with Swords DanceSwords Dance-To set upEarthquake-STABDragon Rush-STAB, Replacement for Outrage

Ok, next is Charizard

ProsDragon fire type, great dual/mix upDecent/Great base statsGreat ability

ConsHas not that great base stats in Sp. Def and Hp, meaning it probaly wont survive a Earth Power

If youre choosing Charizard, heres an example:

Charizard XAdamant

Flare Blitz- Main Move, STABOutrage- STABDragon Dance-Sets upSteel Wing- Beats up any opposing Rock type Pokemon

I would personally go for Charizard, as it is Faster than Garchomp and can learn Dragon Dance via Breeding and can sweep.
