Neither are really known for their padlocks, and they're both pretty hard to find at retail - at least in North America. for a reasonable priced lock (~$20) - I'd suggest American (probably the 1105) or one of Abus' mid level locks. Either are available on Amazon. For "it'll be easier to pry the door off the locker than break the lock" level locks (~$100) - I'd suggest Abloy (330 or 340) or Mul-T-Lock. These are harder to find locally - https://securitysnobs.com/ https://securitysnobs.com/ seems to get recomended on the lockpicking reddit if you want an online vendor. Abloy's "Protec 2" lock design is one of the more well regarded out there- I'm not aware of any credible public claims to have picked it, and short of an angle grinder you won't be getting through the larger padlocks. Trivia - the lock industry is very heavily consolidated behind the scenes, with several companies owning most of the major brands: "Assa Abloy" owns, besides the two companies in the name, Medeco, Yale, Mul-T-Lock, Fichet, and HID - who make the most common RFID security cards. Master Lock owns American Locks.
