They seem to have the same radio hardware so a guess would be the same.
But the Filogic SoC gets pretty hot, so I would worry a bit without active cooling in a boiler room...
Yes and they come with a nice picture frame to hang on the wall. You could print out a sheet with your avatar eye to put in it - Lynx is watching 
Better than GL-B3000?
support wise (and routing performance wise), MediaTek will "always" beat Qualcomm.
Wireless wise, not a lot of difference apart from the lack of external antennas.
Only time will tell.....
based on what we know today, MT have better Linux support than QCA.
in the future, who knows.
QCA is one thing, but ipq50xx is pretty new and a tad temperamental on top, therefore the b3000 wouldn't be my choice.
The active cooling in the MT3000 is thermostatically controlled (and very quiet).
Mega dust will be a problem even with passive cooling as airflow is always present be it forced or convection.
In a similar situation I put an mt3000 in a homebrew hop boiling filter bag - did the job.
It is not huge volumes of heat from the SoC, it is just the temperature vs heatsink size.....
I read that the GL.iNet GL-B3000 has 4 high gain fixed antennas. How would this compare to the two small movable ones on the MT3000 or the TR3000? Surely the antenna configurations make a significant difference?
Which might one expect to work best in crappy RSSI environment (low noise, just weak signal). Live in remote area!
I keep hearing this, but I have had four B3000's running in a mesh for months now and one more used for testing all sorts of things. No issues at all so far....
Is this the 256MB flash version?
256MB flash version is only available in CN, AFAIK.
Oh wow, thanks a lot for exposing this.
What’s your best guess as to how this would compare with the TR3000 with its movable antennas? How does the wifi connectivity on your B3000 compare with the MT3000’s?
Am I right that those antennas are larger? So doesn’t this help?
it really feels like you're overthinking this 
if you can squeeze a single pair copper wire (of any kind) into that hole in the wall, I'll give you a set of VDSL ethernet extenders for free 
Thanks for the offer. Yes guilty as charged - I suffer from OCD, albeit I’ve managed to leverage it for my work. I really dislike running cables as it involves messy interaction with the physical world, whereas the realm of WiFi is super appealing because the messy interaction is with the ether and somehow a much purer experience in my irrational mind.
No, just a different format. For each frequency they are the same size inside, the metal bits anyway, because - physics.
External antennas are (usually) better because they are away from the innards of the device. It is always a bit of a compromise.
No measurable difference in connectivity in use. The mt3000 has a greater range/penetration particularly in ax device to ax device (router to router etc) as the beamforming functionality comes into play and the external antennas seem to do a better job.
Well yes, possibly. Threading a single pair of copper wire is probably not much easier than threading an ethernet cable to be honest (threading anything depends on what is in the wall as well as behind it).
OK excellent - then based on this whole discussion I’m leaning to trying out the Cudy TR3000 and risking the overheat (the boiler room is well ventilated to the outside, and I don’t expect heavy usage). Fall backs include: either a second TR3000 on the other side of the wall - the @bluewavenet wall-wall hack; stuffing a cable through the radiator pipe return hole (albeit this would be a kind of mental torture for me); or probably better having electrician drill a hole later on when all the internal insulation, cabinets and stuff are fitted and we can determine optimal placement etc. - he can then do that when I’m at the office and I just come back and see the shiny ethernet socket.
That's the way! 
Get him to put in a power outlet next to the ethernet socket - job done and the balance of the universe is maitained! (make sure to tell him to vacuum up any dust he makes on those lovely polished copper pipes...... )
Why does this list 256MB RAM in several places I wonder:
But here states 512MB RAM:
flash <> RAM, you previously asked about flash.
it got 512MB RAM, I got one.
just like the DAP-X1860, product info doesn't always match reality
