Hmm I still don’t know why your comparing this to a Noble you’d be better comparing to an ampeg B15, SVT IIP, or an ashdown ‘lil bastard’,
The Noble is a tube DI, it’s not an amp designed to get gritty, overdriven fuzzy or synthy(sic)
The Noble is a one trick pony because it’s meant to be just that. It’s warms the tone with the tubes and allows clean boost of the bass and treble without distorting.
The fact you had to buy a separate DI puts the TBT in a different class of box and indeed it was designed for and is a guitar class A 2.5 watt power amp/preamp in stomp box format, although it has found other niches in studios.
Im sure it’s a great piece of kit and I’d sure like to try one.
However take the Noble for its purpose of a tube DI and compare the BTB In the same parameters and then the Noble wins.
TLDR: TBT is a 2.5watt guitar amp/preamp, the Noble is a clean Tube DI, no comparison.
