If speaker B is in fact 98dB/watt at 1 meter, same as A, then they will sound the same on the 14 and 8 ohm taps respectively. Assuming you have those taps, and assuming the transformer is wound so that there is no practical difference in its performance on those taps.
But it is very likely that the speakers are rated dB/2.83v at 1 meter. This is a sensitivity rating, not an efficiency rating - even though it is far too often claimed to be an efficiency rating. In that case, the 14 ohm speaker is nearly 3dB more efficient and will be louder.
This confusion has been around for decades, so I have no expectation that it will go away anytime soon - there are still flat-earth believers, after all.
