Short answer: the JBL Partybox Encore Essential for value, the Boombox 4 for output in a smaller body. The Encore Essential is a great sounding speaker with somewhat boosted bass, but only 6 hours at medium volume. The Boombox 4 has pretty insane output capability for its size, but it is pretty overpriced for the category at $549.95 against $329.95.
Buy the JBL Partybox Encore Essential. It is rated higher for sound quality than the JBL Boombox 4 and costs less, so only choose the other one for a particular feature it does better.
There is a real battery-life gap here: the JBL Boombox 4 is rated for 28 hours, the JBL Partybox Encore Essential only 6 hours.
There is a real gap in water resistance: the JBL Boombox 4 at IP68 (extended submersion) against the JBL Partybox Encore Essential, which has IPX4 (splashing).

JBL Boombox 4: $549.95 Amazon B&H Photo Video eBay
Older models: the JBL Boombox 3 (ranked lower, rated 3.8/5), the JBL Boombox 2 (ranked lower, rated 3.5/5) and the JBL Boombox (ranked lower, rated 2.9/5).
Pros: Pretty insane output capability for the size. IP68 protection and Auracast pairing with other current JBL speakers. Measured bass extension of 41Hz (-10dB).
Cons: Pretty overpriced for the category. Better than the Boombox 3 mostly because there are more 7 EQ bands instead of just 3 and it can be better tuned. Try Oluv’s EQ for it. Out of the box sounds worse than the Boombox 3. No Aux input.
