Short answer: the Marshall Middleton. It ranks #33 of 120 large speakers by sound quality, rated 4.0/5, at $257.52; the Turtlebox Cub ranks #85, rated 3.0/5, and costs $330, so there is little reason to consider the other one.
The Middleton has very deep bass for its size, to about 39Hz, but forced DSP echo that cannot be turned off, a rolled off treble and flabby bass. The Cub has only listening impressions so far: loud for its size, warm and bass-forward, with some bass loss at high volume.
Toughness: IPX7 for the Middleton, IP67 plus crush resistance for the Cub.
Features: the Middleton has stereo from one unit, an aux input and a built-in microphone. Both have a USB-C power bank.
Battery and weight: 20 hours and 4 lbs (1.8 kg) for the Middleton, 14+ hours and 5.3 lbs (2.4 kg) for the Cub.
Buy the Marshall Middleton. It is rated higher for sound quality than the Turtlebox Cub and costs less, so only choose the other one for a particular feature it does better.
