Should I fund my TD Ameritrade trading account with DBS or Standard Chartered?

TD Ameritrade users, which method of funding the account will better in terms of currency conversion?

1) using DBS electronic transfer SGD to TDA (1SGD = 0.7384USD) (But TDA state that DBS customers have preferred currency conversion rates as they are partners)

2) using Standard Chartered to remit USD direct to TD Ameritrade wells fargo bank under "wire transfer" (1SGD = 0.7364USD)

Rate quoted are from bank websites as of 16 Nov, any TDA users able to share on the currency conversion rates??
