Plaits is the next generation of Braids. I own the Braids module. The Plaits has more possibilities, but the Braids at least has a crude screen for menu diving. However the Braids is higher in fidelity and has more options.
Plaits/Braids are great when you want a sound quickly without a lot of patching and tweaking. If you're short on kit, then they have some great options. Braids can quantize your CV for you as well as apply its own attack/decay if you wish. If you get the micro-version, it's pretty handy to keep around for that extra voice to add some depth to your patch (like a counter melody or some background funky-ness). But 99% of the time, it's not my go-to module as it lacks a lot of features you'll find on a traditional oscillator.
