Generally better features out of the box, and generally better build quality and QC. Basically the only thing Creality has going for them is name recognition among people outside the hobby, which means they end up being a LOT of people’s first printer.
If you are looking for minimal fussing about, get a prusa or a bambu. You will spend more money that route though, and the bambu is a closed system so you buy official parts from bambu when something breaks. Personally I am a fan of sovol and elegoo printers over reality, if you are looking for a bed slinger design. (creality is the name everyone recognizes so they have market share, but really they aren’t making anything better than (or in many cases even as-good as) anyone else.)
I’m also a big fan of flsun deltas, but don’t think I’d go for the v400… Super racer is a great machine and the q5 is a fantastic starter printer and cheap to start, if a bit limited in build area. But if I had the money to spend on a v400 I’d likely buy a bambu (or build a rat rig or voron, actually) instead.
The learning curve is steeper mostly due to tools not having as intuitive names and ui layout.
I dove into fusion 360 last year and was making functional and nice parts within the first couple of hours. Since moving to Linux I’ve tried freecad and while I can eventually find the tools that do the same things, it is less intuitive to get there.
Additionally, when I run into a roadblock in fusion 360, I can usually find quick and easy explanations or tutorials for it, and just have not had the same luck with freecad. I can usually get the hurdle crossed with the tutorials but I find I have to look up the same stuff often as it doesn’t stick.
This is all nebulous as all hell, I admit. And I can vaguely tell that it does all the same things similarly to fusion 360, but it’s just different and obscured enough that I feel useless and obtuse using it and spend more time searching for tutorials and answers than I do designing.
I want to learn it. I want to use it. But I still find myself in fusion 360 when I need to get a part designed sooner rather than later - it took less effort and faffing around to get fusion 360 working in proton ge than getting to a stable point using freecad.
