Best eBike brands overall

Hey everyone!

I'm diving deep into planning my next eBike project, and it got me thinking about the core components. When it comes to custom builds, what brands do you all consider the absolute best for things like motors, batteries, and even frame geometry that lends itself well to modifications? I'm curious if there's a consensus on which brands consistently deliver top-tier performance and reliability for those of us who like to tinker and build our own perfect machine, whether it's for urban commuting or off-road adventures. What are your go-to brands and why?
