These are not really the same size class, and that is the honest framing here. The Marshall Stockwell II ranks #11 of 82 large speakers by sound quality at $229.99; the JBL Flip 6 ranks #12 of 144 medium speakers by sound quality at $129.95.
Why pick the Marshall Stockwell II: Marshall Stockwell II uses 3” woofer, 2x 2” fullrange tweeters. The tradeoff: Bass is limited by its 44Hz specification.
The case for the JBL Flip 6: A very neutral speaker, very small, almost pocket size, a huge sound quality leap over the Flip 5. Watch for: Not stereo.
Buy the Marshall Stockwell II at $229.99 for a large speaker, or the JBL Flip 6 at $129.95 for a medium speaker instead.
If battery life is a priority, the Marshall Stockwell II is rated for 20 hours versus 12 hours for the JBL Flip 6.
There is a real gap in water resistance: the JBL Flip 6 at IP67 (brief submersion) against the Marshall Stockwell II, which has IPX4 (splashing).

The Two Speakers In Full
Marshall Stockwell II: $229.99 Amazon eBay
Newer model: the Marshall Stockwell III, rated 3/5.
Pros: Marshall Stockwell II uses 3” woofer, 2x 2” fullrange tweeters. Its 1.4 kg, claimed 20 hours (Manufacturer specified) battery life, IPX4 protection, aux input, up to 96dB and mono playback make it a practical option for its intended room or portable use. Possibly the most natural sounding Marshall speaker, with excellent off-axis sound. Measured bass extension of 44Hz (-10dB).
Cons: Bass is limited by its 44Hz specification. There is no companion app. No EQ adjustment. Not very loud, and the added DSP reverb may annoy purists.

JBL Flip 6: $129.95 Amazon B&H Photo Video eBay
Newer model: the JBL Flip 7, rated 4.2/5.
Pros: A very neutral speaker, very small, almost pocket size, a huge sound quality leap over the Flip 5. Measured bass extension of 56Hz (-10dB).
Cons: Not stereo. Some slight upper mids emphasis. The TL version (made in Vietnam) tweeter can sound somewhat scratchy and doesn’t sound as good as the GG version (made in China)
