Advice for pure reliability?
Mine is getting close to 1000 hours and it's been boringly reliable. Everyone mentions Bambu, but I'll throw the SparkX i7 into the conversation. Mine is getting close to 1000 hours and it's been boringly reliable, which is exactly what I want from a printer.
I've printed PLA, PETG, and TPU since day one, mostly using stock profiles. No major failures, no endless tweaking, and no constant repairs. Just load filament and print.
If your main priorities are reliability, easy maintenance, and a machine that can keep running for years, I'd definitely put the SparkX i7 on the shortlist alongside the usual recommendations. Real-world experience matters more than marketing, and so far mine has been a true workhorse.
I Tested the 3 Cheapest MultiColor 3D Printers (Bambu Lab A1 vs Creality Hi Combo vs Sparkx i7)
The Sparkx i7, a new multi-color 3D printer from Creality's sub-brand, shows promise in monochrome printing with defined details but suffers from unacceptable and consistent layer loss issues in multicolor prints, making it currently unrecommendable.

Both A1 and SparkX i7 are products targeted for people that want an easy experience, ie they want a machine that work without the owner had to know what is doing. A1 means you must enter they're closed ecosystem.
If you only print things you download from the web and don't mind spending on bambulab filament then A1 is the best choice.
If you want a more open system where you can make custom tags for any spool you want to use and not having to manual set parameters if you prefer to use cheap brands, or if you know what you are doing and want to crate things, know or want to learn how to slice, then Creality is better.

If you are not in an hurry you can wait for the Ender 3 V4 Combo that is basicly a better one, still a cartesian machine, but with the full CSF instead the Lite one, and i just saw on the eu store at the same, or similar, under 400€ price.
This Clone Has No Soul | Creality SparkX i7 Review
The Creality SPARKX i7 is a physically competent 3D printer capable of high-quality prints, but it falls short in user experience due to poorly tuned software profiles and a basic multi-color system, making it less beginner-friendly than its inspiration.
Want to get a 3d printer but can't decide between Kobra X or A1 Combo
I know this wasn't one of the options you mentioned, but I'd honestly take a look at the SparkX i7 as well.
Mine has over 500 hours of printing time since coming out of the box and it has been essentially trouble-free. No major repairs, no constant tuning, no endless troubleshooting.
I regularly print not only PLA, but also PETG and TPU. I've completed multiple TPU prints lasting over 50 hours without a single issue, which says a lot about the extruder and filament handling system.
It's slightly larger than the A1, supports multi-color printing, and in many regions it's actually cheaper than an A1 Combo.
If your priority is reliability and not having to tinker before every print, it definitely deserves a place on your shortlist.
