I have been contemplating this on and off for months. So I decided to ask the people who have the service what that think over on Google+ and I have gotten a large response of opinions.

Should I switch to T-Mobile?
The answer is looking like, yes; as long as there is decent coverage for your everyday day travel.
If you have switched from Verizon to T-Mobile please leave a comment below telling your experience.
Many organizations from, the government to retailers are able to track your movements via your mobile phones MAC (Media Access Control) address. This still is possible when you WiFi is turned off due to your phone sending out this information within a certain range.
It’s not a big step to couple this to personal information – a retailer for example, could track your trip to the register and correlate with your payment information. Now the tracking hardware and software vendors, the store (or chain) owner, their business partners, they can now all track where you are every time you come into range of one of their systems, and fully profile who you are, what you do, your financials, and your daily patterns!
What is Pry-Fi?
Pry-Fi is a solution that does not require us to shut off out WiFi completely every time we leave our home or office. The only way to really ‘shut down’ your WiFi so you are not traceable is to also turn off ‘background network scanning’, and very few people know where to even find that setting. However, shutting down all of this info will loose benefits of modern WiFi like automatically connecting to networks you know; as well as helping the location awareness of certain apps.
Pry-Fi helps us avoid all of that mess by creating a false MAC address that follows the correct patterns to seem ‘real’. This allows trackers to not pick up on your devices real MAC address keeping you safe. Because the trackers are getting a false MAC address your specific address will never be recorded and the next time you are within their range a new MAC address will be created by Pry-Fi preventing them from gathering the correct information.
This will slowly poison their tracking database with useless information.
Go To War!
This option allows your device to ‘pretend’ to be dozens of MAC address wandering around the store or other location. It only takes a few minutes of walking around with this setting enabled to ruin their tracking data. Of course companies say they do not use this information against us, but we all know that if something can be abused it might as well have already been abused.
Message from the Chainfire team:
It has been tested on several devices and seems to work, but it is very young still. The magic the app does to achieve its purpose is ever subject to changing Android security policies and OEM customizations, so even though it works now, there really is no saying if it will still be possible in future firmwares.
Of course you should also keep in mind that tracking can be done in many ways, and these W-Fi signals are far from the only method in use.
