BEP 20 is cheaper compared to TRC 20 you have to pay less fee in BEP20 while in TRC 20 charge one dollar fee so I will recommend you  BEP 20.
 The time required for transactions bath are approximately same but fee is a bit higher for TRC20 so we should use BEP20 which is quite cheap so we should use it because what we need is cheaper than the expensive one. If we get it, we should choose this thing because we should not waste the dollar that we have, we have it is better that we  use in the transaction. Only for the fee because the fee is less and we benefit from it.
