The bottom one. Easy question.

The top is west coast sound, the bottom is east coast. The difference isn't dramatic, but it's easy to see in the shape of the response.

The bottom graph has a mildly crowned shape, fairly flat from 200-1KHz but sloping down above and below that. The shape of the curve from 200Hz on up will make this a "natural" sounding speaker for most people, although some who like a brighter (they would say neutral) speaker will hear a little midrange emphasis. Based on this shape, I would expect the soundstage presentation to be a little forward as well. The slight bump around 200 Hz and the higher output in the upper bass relative to the mid-bass will also make this speaker sound "full". Considering this is an anechoic measurement, the output at 45Hz is relatively high and may cause one-note bass in some people's rooms.

In contrast, the upper graph has a mildly dished shape, which will give it a slightly "west coast" sound. Some people will call them neutral and some will call them bright. The center of the dish is around 1.5KHz, which will give it a slightly distant and deeper soundstage presentation, which along with the rising treble response will probably make these sound more spacious and airy. The upper speaker should also have cleaner sounding bass in most rooms and covers the bottom octave which the upper speaker does not.
