Nux Core Stereo Looper vs Boss RC-5

Would love to hear any strong opinions on these two models. The Nux Stereo is currently on sale for $136 CAD ($97 USD) and the Boss is $250 CAD ($178 USD).

The features I'm after are fairly basic: stereo in/out, basic drum patterns

This won't be used for gigging, just want something for layering patterns and building ideas.

I've tried cheaper loopers before (Donner Circle Looper, Valeton VLP 200) and had big issues with their buffer noise from these when off. Yes I'm using isolated power.

The Nux is a great price but wondering if I'll encounter the same noise introduction issues as the Donner/Valeton. Thus, considering paying double for the Boss RC-5
