I bought my V1 VT Bass when it first came out and I still use it as my main preamp. I've tried a few other preamp pedals but the VT always ends up winning.
I also have a copy of Helix Native and I'm not really a fan. I don't play out anymore so I don't have a need for an amp since I just play at home. I use my pedalboard into an Element loaded with some various cab sims and that goes out into reference monitors. That setup beats the Helix or any other amp sim that I've tried for both recording and playing.
More or less in the same boat here. I've had a VT for years and it's my main recording interface for my basses and is the last stage on my pedal board. I've considered getting the V2 version of the VT but my current box is doing the the job just fine. I've given Helix Stomp and Native shots--sold the Stomp fairly quickly--and neither offered anything on the bass front I'd use as an amp sim, which is totally mystery to me, as I'd had one of the old Bass Pods back in the day, and it was great. I've given Logic's built in stuff a spin too and had a little better luck than with the Helix stuff, go figure. I own the Amplitude Ampeg and Fender plugs but they've rolled that into some bigger package I don't feel like messing around with.
