Which of Soundproof and Bulletproof is generally better for Kommo-o in National Dex Monotype?

Question

I've been playing National Dex Monotype lately and this has been on my mind. I've been using Bulletproof to block moves like Shadow Ball, but almost every other Kommo-o user I encountered has Soundproof. Soundproof can block other Kommo-o, sound moves, and Ditto using your Dragon moves (to some extend), but I find that Mega Altaria can take care of those just fine. Here is my moveset for context:

Kommo-o (F) @ Kommonium Z
Ability: Bulletproof
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Clanging Scales
- Aura Sphere
- Flamethrower
- Substitute

Sorry if this question isn't allowed since it's already been asked a million times.

Answer 1

You'll usually want Soundproof

Even though you said that your Altaria-Mega takes care of opposing Imposters quite well, it'd force you to switch, which'll stop your sweep. Now this is something which I'd personally hate, as a stupid Imposter, getting a free chance to come in (after a kill or a slow VoltTurn or w/e), is forcing a switch. Meh. Bulletproof, even though pretty nice, is conditional (and so is Soundproof, but you'll want some answers to Ditto), and it prevents your sweep against Imposters.
Even Kommo-O's Smogon Analysis states the same thing:

Soundproof is used to make Ditto and opposing Kommo-o unable to revenge kill Kommo-o with Clanging Scales.

So, you'll mostly be going for Soundproof than Bulletproof.

Hope it helped!

Ah okay, but locking Ditto into a dragon move and using Maltaeia is fun

Yeah that's pretty cool, but tbh both the abilities are conditional/situational, and Bulletproof overall has more pro's as compared to Soundproof, so yeah it's better and more used. And if you switch out the Kommo-O, it might just become deadweight, as it's checks/counters would be able to check/counter an unboosted Kommo-O better than a boosted one :3.
