I can't comment on the other ones unfortunately, but there are a ton of mods available for Vorons that are still coming out. They're solid platforms and great if you're someone who likes to tinker, imo they're also super solid as "just print" device. I've got mine with canbus and built a filament changer, but there's tool changer mods I've seen as well.
If you do go for a voron, I'd suggest a trident. I have a 2.4 but I recently built a fixed gantry printer like how the trident is setup, it's a lot easier to work with.


Just make sure you've got good gloves/respiration and ventilation if you go MEK, as far as I recall it's not nearly as aggressive with petg like acetone and abs so going to take some time. The solvent method is by far the one I use the most often, I wet a rag or paper towel and take my time. I recall vapour smoothing being a thing too but that's going to need setup and the like.
