if you are using Oanda, you pay $1.5 round trip (the spread only). If you are using average broker, you pay $3 round trip (the spread only). If you are using EFX, you pay $1.28 (commissions) and $1 (the spread, if it's 1 pip) = $2.28 round trip.
In a sense, yes, spread is apples and commission is oranges, but together they make up for the total cost (all the fruits)

Anyway, Oanda offers only 50:1 leverage which is a great disadvantage to EFX.
