RE: Sold my H2D....
I do not share your experience. My Core One just works no matter what filament I choose (within its scope) and no matter what size print (as long as it fits). I get an occasional warp on any machine, including Bambus.
Yeah, I will say the Core One works better than printers like the P2S for things like PC, ABS, and ASA. That said, large objects have been a challenge in both.
The H2C and the H2D along with the X2D have just worked.

RE: Sold my H2D....
To this date, I have not needed a heated chamber. I have several printers with them but most do not, and I have not seen a difference in print quality. PEEK requires a heated chamber, but you are not printing that on an X2D.
Depends on what you are printing. If it's PLA/PETG/TPU then definitely do not need a heated chamber, in fact it will cause issues. PC, PA, ABS/ASA for example does for larger parts, but for Benchy sized stuff then no. I would agree that the majority of 3D printer users probably don't need a heated chamber. A closed chamber however is very useful with regard to filtering of VOCs and harmful gasses like styrene etc.
I do not print PLA. I print mostly ABS, ASA, and PETG.

Really depends on the material. The Core One's passively heated chamber is perfectly adequate for ABS and ASA but not so much for large PC parts. When I finish work I'll upload so photos of PC parts printed on the Core One versus the H2D. The degree of warping is more pronounced on the Core One, especially closest to the door.
But, to the point, I would argue that 90% of hobbyists (I'm making this up...) probably don't need an actively heated chamber. I had some very specific use cases that the Core One couldn't handle which is why I bought the H2D. I will still keep the Core One though because it is waayyy more easier to print TPU on it and with the INDX multi-color is (will be) better.
RE: Sold my H2D....
Perhaps this is what we are getting wrong. With the introduction of more and more tool changers what if we ended up just using engineering materials ONLY where they are needed.
Warping will no longer be an issue as much smaller sections of the material will be needed or used. The rest of the model could be printed in another material that is yet compatible with the temps used, but less prone to warping.
Regardless to say, after 3 different bambu models, I can see they do not speak to me and my workflow, hence why the H2d was sold. Most interesting experiment was that even using tuned parameters, the Core One returned way better Nylon prints than the H2d... You would have thought that the hotter chamber was a the better choice, but it was not necessary in the end.
I feel the H2d and bambu lab in general are made for automatism and PLA PETG mass production in multicolor. They seem to do well there and I hope the INDX is just as good or better.
On that note I am now on the fence to either wait for INDX or buy the CORE ONE L now. I can't decide. I wish Prusa moved faster .

Nylon is a bit of an outlier and you are right, I tend to get better prints with it on the Core One. But I think the variable here is the nozzle and not the chamber. The standard H2 steel nozzles don't print as well as the Nextruder versions. The exception is the H2D Diamondbacks. I haven't noticed a difference between the two.
For sure though, there are filaments that I just cannot print on the Core One. The other issue is support material is just not practical on a Core One either. That will change with the INDX but only up to a point.
RE: Sold my H2D....
curiously why do you think support materials won't be as useful on the core one with INDX?
don't get me wrong, I have been having an absolute freaking blast with the H2 D and the H2 C…
RE:

Depends. PETG on PLA or vis-versa, it's a tie, i.e. the H2D and C1 INDX are the same. If I'm printing PC or ASA with a HIPS interface (which I do a lot) then I need an actively heated chamber. Also, with the INDX I'm limited to passively heated around 50° or so assuming I have the top-hat thing on. Then there is the build volume difference as well.
RE: Sold my H2D....
You have C1? Not C1L?
With C1L I get easy 60celcius with an isulation board on the top of the printer.
