Megastone -- Garchomp or Metagross?

So I have 5 of 6 Pokemon decided for my Battle Tree BP grinding team. But I’m having a bit of a hard time deciding how to fill that 6th slot. This got me thinking about which Megastone I should use.

I had originally been planning to have my Metagross have it’s Megastone. But one of my candidates for the final slot is Garchomp. Both Mega Metagross and Mega Garchomp are incredible physical powerhouses with few weaknesses and some pretty devastating movepools.

Which is generally considered to be more valuable to a team, Mega Metagross, or Mega Garchomp?

The rest of the team, as per request. Note that I’m still putting details together, so some bits are not yet hammered out. In truth, I haven’t really decided on Garchomp yet, but I am in need of something more than just Toxapex to deal with Fire, specifically. Other contenders were/are Flygon, Milotic, Gyarados, etc.

I believe that you should get Mega Metagross instead of Mega Garchomp, because Garchomp doesn’t really need a mega.When Metagross becomes mega, almost every stat (HP not included) gets a pretty huge boost. Its speed becomes higher than average, its attack, defense, special attack and special defense are also boosted a lot. However, the HP isn’t a huge problem because it is steel type (steel types are resistant to a lot of types) and it has easy access to powerful and (possibly) unpredictable moves. Simply look up Metagross on Smogon or search for a few good movesets.

However, for Garchomp it doesn’t need a mega. Sure, its base stats also become 700, but its speed is slightly lowered, it loses its great abilities (did I mention that Mega Metagross' ability is very useful?) and its special defense is barely boosted. There are barely any advantages for Garchomp’s mega. It’s just sort of useless.

So, you should get Mega Metagross. It gains a very good ability and almost all of its stats are boosted a lot.

I would do metagross since garchomp losses speed when mega evolving

in my opinion you should get metagross for two main reasons

garchomp is believed to be better than mega-garchomp because of losing its ability and a big speed drop

mega-metagross has the highest bst in the over-used tier (the tier directly under ubers)

Recommended for metagross (MOVESETS: -Move 1 -Meteor Mash as you commented|-Move 2 Earthquake as you commented again|-Move 3 -Brick break good for dark types and all other that are weak to fighting|-Move 4 -Agillity as I recommend it because it will be great for a setup on speed if your a fan of speed)

Recommended for garchomp (MOVESETS: -Move 1 -Rock Tomb I beat alot of mega charizards with this move also it lowers speed which is great| -No more ideas for moves I will come back here again with awesome moves again expect I to find the moves match) I would take metagross anyways I’m still a big fan of garchomp…
