[I'm New] Which Big Six variant is better for ladder/Bo1?

I’m still pretty newish to competitive 2v2. I’ve reached Master Ball, but I’m still learning matchups and how to pilot teams properly.

I’ve been trying these two Big Six variants:

Variant 1

• Whimsicott - Focus Sash - 6 HP / 28 SpA / 32 Spe
• Garchomp - Life Orb - 32 Atk / 32 Spe
• Kingambit - Black Glasses - 31 HP / 8 Atk
• Mega Floette - 2 HP / 32 SpA / 32 Spe
• Mega Charizard Y - 21 Def / 21 SpA / 24 Spe
• Basculegion - Mystic Water - 12 HP / 32 Atk / 8 Def

Variant 2

• Whimsicott - Focus Sash - 2 Def / 32 SpA / 32 Spe
• Garchomp - Sitrus Berry - 29 HP / 15 Atk / 4 Def / 2 SpD / 16 Spe
• Kingambit - Chople Berry - 28 HP / 5 Atk / 1 Def / 32 SpD
• Mega Floette - 1 HP / 1 Def / 32 SpA / 32 Spe
• Mega Charizard Y - 16 HP / 31 Def / 14 SpA / 5 Spe
• Basculegion - Life Orb - 4 HP / 28 Atk / 11 Def / 8 SpD / 15 Spe

I hear Variant 2 is the more popular/common version, but Variant 1 feels much easier for me to play. I struggle more with Variant 2, while Variant 1 feels more straightforward and gives me clearer win conditions.

Which version do you think is actually better, and which is better for someone still learning?

Also, is Variant 2 more suited to tournament play and specific matchup prep, while Variant 1 is better for random Bo1 ladder games? Or is Variant 2 simply better once you learn how to pilot it properly?
