Faster CPU than the original Pi 3 Model B
Thanks to a new thermal management plate (heat spreader), as well as better voltage regulation, the CPU gained a nice little 200 MHz bump in clock speed over the Pi 3 Model B. Applications on the Pi 3 B+ are a little faster and snappier than their predecessor.

Superseded
the newer Model 4 is available for the same price and can do everything this does and more.

World-class support and software
What really sets the Raspberry Pi apart from the competition, and makes it leagues apart from every other SBC out there, it the software and support you get from every corner of the ecosystem regarding anything you want to make, build or do with the Pi. The most up-to-date kernels, the widest supported bundles, hats for every occasion, step-by-step instructions, and if you're trying something and get stuck, chances are high someone else has got stuck at the same spot, got past it, and left detailed instructions on how to get past it so nobody ever gets stuck there again. That is the best feature of the Raspberry Pi.

Con
USB and Ethernet bandwidth shared
For cloud servers (OwnCloud, NextCloud, FTP, Media Hosting, etc...) it will take a dip on the transfer performance (when using ethernet combined with a USB Storage device) as the same controller handles the USB and Ethernet interfaces. Better performance than its predecessor, but something to keep in mind.

Faster networking capabilities
Because of the Gigabit ethernet (although still sharing the USB 2.0 bus which limits its speed ceiling), it goes up to 3x faster than the original Pi 3 Model B. The new wireless chip supports 802.111ac, which also increases its throughput to 3x as well. Bluetooth 4.2 LE is much more stable, and it's just a nice little upgrade.

Con
Only USB 2.0
It only has USB 2.0 ports which are painfully slow but they are also limited to 0.5 A which is not enough to power a HDD reliable.

Great community and developer support
The various addons boards means this is the board to go with for starters into development. Without much knowledge you can get a project up and running in a short amount of time.

Con
Not for power users
The Pi has a 5V/2.5A DC power input which is not enough.

Con
Bluetooth is very unstable - never fails to fail
Many times after successfully pairing devices it just stops working. One speaker worked for about 5minutes then stopped. Since then it will pair but will not connect. Yes the speakers work in Windows and with a Samsung Galaxy S8. Its seems to have more to do with the Raspbian OS, since using a BlueTooth dongle with it gives the same results.
