I have experience with the Voron 2.4. I built mine a little over a year ago and absolutely love it.
The V2.4 crew pride themselves on print quality. I mean, just look at what is required to be part of the PIF (PrintItForward) program. I can personally attest that print quality is amazing, and I have printed ABS, ASA, PLA, and PETG and had success with all. The enclosure can be built with easily removable clips so you can change from one setup to another.
There are also tons of mods out, like the Nevermore, which would help reduce those bad air particles from printing ABS.
I've heard of V2.4 printers reaching 300mm/sec print speeds. I usually run everyday prints around 80-150.
If you want to eventually try multi-material printing, then you will want to check out the ERCF project.
You should know that the Voron build process is maybe 1% of your work on this thing. You will be tinkering with ini scripts and print settings for years after your first benchy. For example, you'll probably want to install the Klicky mod (or some other Z probe mod) and Auto-Z leveling. With QGL and Auto-Z your prints will start within roughly 0.02mm of the perfect first layer every time. But all this will take time to setup and configure.
On top of all that, the Voron discord community is amazing. If you need help with a print issue, someone will help you.
If you have any other questions, lemme know!
Fair, but it is worth pointing out that the PIF program aims for better quality. Boggles my mind why they shipped this set if it has such clear issues.
