Even at 110 Str the triple andre is probably better. You need to have 15 % of your atk > 60 atk (from andre). So you need at least 400 atk to make the 15 % card better.
Edit: Hmmm.... well .. if you have Porcellio Wings (50 atk) and a Bloodied Shackle Ball+Shackles (another 50 atk) and a Giant Whisper Card (20 atk) you only need 280 atk. Gladius is 105 atk so you only need 175 atk from your Strength. You reach that at 94 strength. If you have those equips you don't bother to use a "15 % versus everything"-Gladius. Whose idea was that weapon >_> ?
