best os for the raspberry pi model b+

There have been more OS.

- Linux branch, Debian, CentOS, FreeBSD, Ubuntu,

- CMSIS supported, Mbed OS,

- Kind of RTOS, zyphre, rt-thread

- Windows IoT

- Android Things

Since it is based on ARM-Ax, nearly everything can be ported. And more can be added to this list.

G'Day,

I use Raspian exclusively since taking a slice in the model of a Pi B.

I have yet to find a reason to explore other O/S's.

I didn't check the date! Not sure why, but this old poll popped up as recent and I answered it.

"You forgot Windows 10 IoT. Actually, maybe you didn't."

Not sure that was around in 2014 when the poll was published

You forgot Windows 10 IoT. Actually, maybe you didn't. I tried it and unless you're really tied to an application it's not really ready and probably never will be.

Seriously though - it will depend on what you're doing with the Pi.

NOOBS is not an O/S, but a package of other O/S like Raspbian Arch etc. If you have a big SD card up to 32 GB, NOOBS allows 2-3 choices at boot time of say OpenELEC and Rasbian for example...
