I love it. It's reliably worked well for me since 1.1 and is an essential part of my workflow. Not much more to say.
I've had this argument a million times on here, and I should know better than to get into it again ... but ... imho the whole "Overbridge is bad because it steals resources" argument is based on a bunch of very questionable assumptions about how Elektron structure their business.
Especially, it assumes that it's a zero sum game as between hardware and OB development - I don't see how that's the case, it seems reasonable to me that they actually got a bunch of extra sales of the Overbridge enabled analog boxes that they wouldn't otherwise have gotten.
I personally bought both AR and A4 rather than a Tempest and another polysynth/groovebox mainly because of Overbridge, and never considered buying Elektron boxes before then. I'm also very likely to buy a heat primarily for use in processing daw audio through the plugins - that's three sales they otherwise wouldn't have had. Seems to me that OB would pretty much pay for itself on that basis.
Also, both Analog boxes have recently received significant sequencer updates as well as a whole bunch of additional machines for the Rytm alongside Overbridge development, so you can't say it's been an either/or with hardware development. And the Octatrack is now 5 years out from release, it's pure fantasy to imagine that it wouldn't be considered fully feature mature at this point, overbridge or no overbridge.
I understand that Overbridge isn't for everyone, but it's imho absolute bollocks to consistently complain that it's had some massive negative impact on the hardware side or that functionality would keep being added to machines indefinitely if it wasn't for OB.
