Short answer: the JBL Partybox On the Go, if you are buying new. The Teufel Boomster 2021 ranks higher than it (#46 vs #60 of 90 boombox speakers, 3.4/5 vs 3.0/5) but is discontinued, so only consider it used; the JBL Partybox On the Go is still sold new at $300.
On the Teufel Boomster 2021 side: Pretty balanced sound, slightly warm. Watch for: Not as deep of bass as above ranked speakers. Boosted mid bass compensating for the lack of bass extension.
Buy the JBL Partybox On the Go new; the Teufel Boomster 2021 is no longer sold new, so it only makes sense as a used find.
There is a real battery-life gap here: the Teufel Boomster 2021 is rated for 18 hours, the JBL Partybox On the Go only 6 hours.
Water resistance is not close: the Teufel Boomster 2021 is rated at IPX7 (brief submersion), well ahead of the JBL Partybox On the Go at IPX4 (splashing).
