For no apparent reasons, I keep forgetting to give this a serious testrun (well, it's likely because it's in the Bass Amp section). Will finally do so later on.
But seriously, I think there's plenty of pretty decent pedal platform choices already - especially when using real analog pedals, IMO the HX series is doing extremely well. And fwiw, they're working fine in loops IMO, too, but the main inputs take dirt pedals as good as it gets. Even so much better than the Amplifirebox which I'm currently using as the main dirt platform channel on my board that I'm tinkering about a new board routing since a while already (HX Stomp only serves as an FX unit atm).
