I mostly called it a step up since I paid a zero more on the end back when I got the form 1. I've never worked with the anycubic personally so I can only repeat what I have heard in reviews etc, so take that with a grain of salt or 2. First of the anycubic is a darn good printer, as your work well shows! In comparison though, the formlabs machine has a more complex and powerful peeling mechanism which increases reliability. According to a lot of reviewers, the construction of the Z-axis worm gear is also a lot more sturdy reducing the chance of layer shifting and other failures. That being said, if you end up printing everything twice and taking the best result on an anycubic, that might well give you equal results to a form 1 in the long run, for cheaper. of course the form 1 is now long obsolete, as the form 3 is the current machine in production!
