Pros
Pro Fits well on virtually any wrist
The Microsoft Band 2 comes in 3 sizes to ensure it fits: Small (145-165mm or 5.7-6.5"), Medium (160-190mm or 6.3-7.5"), or Large (185-215mm or 7.3-8.5").
Pro Natural feeling display
The display is slightly curved, making it more natural to wear and use. You also won't be hitting it off walls and doors as often as other watches because it doesn't stick out as far from your wrist as other fitness trackers.
The OLED display doesn't light up black pixels, meaning the background blends in perfectly with the bezels making for a more pleasing look as well as saving battery life when displaying mostly black colors.
Pro Custom guided workouts
The fitness tracker allows you to ditch the notebook before heading to the gym.
Pro Smartphone connected
The Microsoft Band 2 connects to your Android, Windows Phone, or iPhone to provide notifications on your wrist. Swiping left from the main screen shows notifications that have been synced from the watch. It doesn't show context for these notifications however - just the number of missed notifications and their respective icons.
Pro Clear, responsive IPS display
The G Watch has a clear, responsive 280x280 IPS LCD with slightly noticeable lack of deep blacks.
Pro About 2 days of battery life
The G Watch has a 400 mAh that lasts for roughly 2 days of typical use.
Cons
Con Band 2 is discontinued - no Band 3 on the horizon
Most likely due to the very high incidence of returns (due to charging issues and the straps cracking in half), the Band fitness tracker brand seems to be entirely discontinued.
Con Poor HR sensor + Poor data visualization
The fitness tracker's HR sensor is very inaccurate during HIIT/weight lifting movements, it takes forever to even lock-on, and once locked-on it doesn't stay locked-on. All of this contributes to very poor HR accuracy. To top it off, the app/web site does not display high-frequency data, it will plot a single HR point for every 1 minute of activity which makes it very, very useless.
Con Bulky clasp
Under the clasp is a sensor that determines whether it's being worn or not (so it can save power when not in use), which adds bulk.
Con Poor battery life
Without using the GPS, battery life can be stretched to a day and a half, but if you do use the GPS that time will be reduced to just a day. Either way, you will want to charge it every night.
Con No GPS
Con No Wi-Fi support
Con Corroding charging pins (can be solved with a software update)
Multiple people are reporting corroding charging pins. Additionally, LG has said that they won't be addressing the issue and there's even a unified attempt from the community to pressure LG in fixing the issue.
LG has released a software patch to address this issue. It should be resolved after applying the patch.
Con Display slightly lacks blacks
Mostly noticeable in direct sunlight, the LG G Watch black levels are somewhat lacking.
