Would Mamoswine or Garchomp fit better with a BellyJet Azumarill in battle spot?

Alright, so I decided I’d take up battle spot after breeding a BellyJet Azumarill of death, who is destroying everything I slap it up against. However I have noticed she does suffer a horrible weakness to Electric, so I decided I needed a ground type. However I’m stuck with either having Garchomp or Mamoswine with an electric immunity and STAB earthquake. Garchomp literally ticks every single box but obviously everyone is prepared about Garchomp.Mamoswine is quite powerful but is a double edged sword, being amazing offensively but has much more to desire defensively. Plus he has a rock bottom speed stat.In your opinion,would Mamoswine or Garchomp fit my BellyJet Azumarill’s need for a ground type to dispel Electric types better?

Garchomp. Like sumwun said, it can counter it’s weaknesses, and it’s faster. I don’t think a Mamoswine could survive a Special Attack anyway, and Fire (Assuming it doesn’t have Thick Fat) and Water is pretty common, SomeGrass Types are common too. (Mostly being Sceptile, Breloom and Amoonguss nowadays.)
