Ok let me rephrase the question, name on SOHC motor that is in the same size car that is superior to the B18A/B. Ther motors listed are like comparing apples to oranges. Those motors have more power and tq but are slow as hell in the vehicle they came in. They will be very hard to swap in a smaller car say civic, integra etc than the B series motors. The aftermarket for those motors might be 20% of what the b18A/B motors have.
