Short answer: the JBL Partybox 330 for karaoke and TV inputs, the Turtlebox Grande for battery life. The Partybox 330 adds an optical TV input, USB-C lossless playback and dual mic and guitar inputs, and is slightly more powerful than the 310 and Stage 320 at 280W versus 240W, though its sound is nearly identical to those two. The Grande offers a 10-inch woofer, an IP67 shell and a 158Wh battery at the cost of claimed specs that do not hold up.

Buy the Turtlebox Grande ($730) for a boombox speaker; the JBL Partybox 330 ($599.95) suits a party speaker instead.
If water resistance matters to you, the Turtlebox Grande at IP67 (brief submersion) holds up far better than the JBL Partybox 330 at IPX4 (splashing).
