Hegen or Tommee Tippee?

Which is better? First time mum here & i would like to take advantage of the upcoming 11.11 sale to buy baby bottles. Im thinking of getting either the Hegen complete starter kit or Tommee Tippee complete feeding set. Both seems great to me 😭 If Hegen, exactly which bottle sterilizer and warmer can be used? Please give the exact brand / name / model. Thank you! :)
