Short answer: the JBL Flip 7. It ranks #14 of 134 medium speakers at $129.95; the Sony ULT Field 3 ranks #57 and costs $148, so there is not much of a tradeoff to weigh.
On the JBL Flip 7 side: A very neutral speaker, very small, almost pocket size. The catch: A little bit of a bump at 4khz, not quite as neutral as the FLip 6. I believe this one is slightly worse than the Flip 6.
The case for the Sony ULT Field 3: IP67 rated, dustproof and water resistant. Set against that: Sounds a bit hollow, a bit boosted in the treble.
Buy the JBL Flip 7 if the ranking matters more than the price. Buy the Sony ULT Field 3 if the price matters more than the ranking.

The Two Speakers In Full
JBL Flip 7: $129.95 Amazon
Pros: A very neutral speaker, very small, almost pocket size. Just slightly more treble than the Flip 6 which was already a great speaker. Slightly deeper bass than the Flip 6
Cons: A little bit of a bump at 4khz, not quite as neutral as the FLip 6. I believe this one is slightly worse than the Flip 6.
