The difference between the Rpi and the AML boards is the level of support. Almost all AML boards are churned out and left to hang out to dry with shitty software and consequential underperformance. Not even AML support their own products beyond churning out substandard Android builds.
The Rpi is more than capable of running LE and because it is well supported by the Pi foundation the LE builds tend to be rock solid and perform very well from very early on. The Pi 3 has its own issues - but in almost every way it is a better most of these AML boxes.
The difference between Pi and AML is just night and day and if it wasn't for the efforts of LE developers beyond the call of duty these boxes would be pure junk no matter what their nominal specs. I have been suckered into buying two AML boxes into my time (the first a pure mistake, the second on claims of company support which simply didn't materialize), and I wish I had have stuck with Pi's both times. The time I have wasted on them.
Well to be honest it's not all rainbows and candy in the Pi land either. How is the official 7" display support? Backlight adjustment? 90/270 degree rotation with touch input? Raspberry foundation has a great track record going the easy way and total silence when it comes to the hard questions (i.e. why is the $5 zero at least $10 IRL?)
Raspberry is good starting point if you want to learn (especially how hypocrite certain humans and communities can be...), but in the long run it is quite useless. There is way better HW to be had for way less money. For a Media box it is quite out dated and slow. You are better of with an AML box.
I have Mecool m8s pro+, with the *faulty* eMMC. (I am still not convinced that they are faulty, probably just use different HW and need some adjustments in the bootloader, I am still trying to find time to investigate this further) I even got 50% refund from the seller, because of the eMMC issue. LibreELEC runs great on it, CoreELEC works even better out of the box! I have HD Netflix on it and it plays h.265 videos without breaking a sweat. How is the h.265 decoding on your Raspberry Pi?
Thinking that people behind Raspberries have any purer motives than the Chinese Android box manufacturers is just ludicrous. The lack of Chinese Android box manufacturers contributing to the Linux mainline effort is obvious. They sell Android TV-Boxes! The chip vendors sell chips mainly to Android devices, so the Linux support is not high priority. This has changed a little and things start looking promising, but still what obligation do they have for the Linux mainline/LE effort?
To not to go totally OT.
It's sad to see yet another fork because of personnel che-mistry* and politics, but if it gets's us better software it's a win!
Only thing I wish is that all the relative information get's put up somewhere asap. Finding it among this thread is going to be a PITA.
I try to find some free time to get some how to's written if I can.
Also, if anyone can point me to some information about the slowemmc releases, what they are for and may they be related to the eMMC block write issues on the Mecool boxes. It would be very much appreciated. Thank you.
*(For some reason che-mistry, whit out the dash, is cencored word in the forums!?!?)
