Pros
Pro Extremely cheap
Intended to be as cost-effective for younger people to learn basics of IT and Computer Science, Raspberry Pi Zero costs around 5$ while it's W and WH variants costs 10$.
Pro Extremely small size
The Raspberry Pi Zero measures only 6.5cmX3cm and is 0.5cm thick. Making it one of the smallest (if not the smallest) single board computer that can run a desktop OS.
The small size makes it extremely portable and manageable, compared for example to the original Raspberry Pi which often looked clunky and large when strapped on something that would be moving.
Pro The largest and most active community
Raspberry Pi has the largest following of any single-board computer. The amount of guides, tutorials and software available for the Raspberry Pi is unmatched by any other competitor. A regular user has close to no chance to run into a problem that hasn’t been covered already. If a web search doesn’t yield any results, the users on the official forums are very responsive and will usually reply within a day.
Pro It for small
great for small projects
Pro Can easily be powered from any external battery pack
Because of its small size and because of the ARM based processor which is extremely energy efficient, it can be run with any kind of external battery pack, even those that are used to charge phones.
This makes it perfect for portable projects that need to be run even when not close to an energy source.
Pro Has three variants
Raspberry Pi Zero has three variants, the Raspberry Pi Zero W, which has a WiFi card included, the Raspberry Pi Zero WH, which has both the WiFi card and has the GPIO headers pre-soldered, and the original Raspberry Pi Zero.
Pro Can run a full HD display at 60FPS
The GPU that the Pi Zero uses is relatively powerful. In fact, it should be able to run a full HD display at 60FPS without any problems.
Pro Easy to install the official OS
All Raspberry Pi boards run Linux as a default OS, the Debian-based Raspbian specifically. Setting up Raspbian on a Raspberry Pi is a breeze and even someone who has not installed an OS before can easily do it.
By simply following the official documentation, you download the relevant software on the microSD card and boot up the board. After this, you can simply follow the instructions to install the OS.
Pro Based on the same Raspberry Pi Hardware
Zeroes are basically trimmed down versions of their larger Raspberry Pi sisters. Trimming out unecessary I/O ports and connectivity ports were done to make the factor of the Zero smaller. As of 2018, Zeroes are based on the Raspberry Pi 2 hardware.
Pro Has extensive OS support
Unlike its competitors, Zero has extensive OS support from the industry, ranging from Windows 10 IoT core, to Alpine's Raspberry branch.
Pro Fast if the OS is compiled properly
If the kernel is compiled properly (like re4son kernel for Kali linux) it's surprisingly fast.
Pro Extremely cheap for what it promises
The Orange Pi PC is extremely cheap, especially compared to the SBCs it competes against.
Pro Supports almost all OSes supported by Raspberry
Orange Pi supports Raspbian, Ubuntu, Android and many more operating systems. It claims to support all OSes supported by Raspberry Pi and it seems to be true most of the time.
Pro Great value for the price
Great little linux box for the price
Cons
Con No Ethernet port
The Raspberry Pi Zero has no Ethernet port, which means that the only way to connect to the internet with it is through a WiFi dongle, the built in WiFi from Zero W variants, or a USB Ethernet port.
Con Has only two micro-USB ports
Due to its small size (and price) the Raspberry Pi Zero only has two micro-USB ports, and one of them is for power which leaves only one port for peripherals.
Con No built-in storage
Like its larger Raspberry Pi sisters, Zero does not come with any internal storage and relies heavily on external storage.
Con Needs micro to non-micro converters
Because Zero uses small factor I/Os, you need converters like mini-HDMI to HDMI, mini-USB to USB-A, to work with this device.
Con No built-in Wi-Fi
Raspberry Pi Zero, by default has no WiFi card. This can be circumvented by buying a WiFi dongle or buying the Zero W, which has the WiFi built in.
Con Has some thermal throttling issues
The Orange Pi can get pretty hot, up to the point where it needs to shut down cores to keep it from locking up.
Con First Party OS support is practically non-existent
Con no wifi
Con Has problems with slow microSD cards
Anything less than a class 10 TF/microSD card will probably not work with the Orange PI. Since the testing and production of the Orange Pi was rushed massively, as a result it cannot step down to be more compatible with slower SD cards. Although it should be mentioned that this is not that much of a problem since you can get class 10 microSD cards for pretty cheap nowadays.
Con No video connector natively
Must use RPIO equivalent to wire any video.
