I ordered from Amazon and I to the model that has the game controller.  
The $149 price is just with the TV remote.  I also wanted to make sure I 
had the smaller Shield which is the latest version. I got P2897. The 
long dimension on the Shield is only ~1" longer than the TV remote. I 
got it on sale just after Christmas for $169. The official name in 
Amazon is NVIDIA SHIELD TV Gaming Edition | 4K HDR Streaming Media 
Player with GeForce NOW.

Well I think it comes down to use case for your TV watching. First My 
Samsung UHD has a few very shitty apps and they are slow on SlingTV, 
Hulu, Prime Video, etc. The HDHR view is not very good for my usage for 
Live TV. There is also no builtin app for Mythtv.  So I can add another 
PC/RP3/Shield to do the mythtv frontend via an HDMI port.  With the 
PC/RP3, I still need a Roki or FireTV stick to get the streaming 
services.  With the Shield I get a Mythtv Frontend, and all the Android 
apps for streaming services. Mythtv doesn't support 4k yet, neither does 
SlingTV. Prime has some 4K. Unless I clean my glasses and stop drinking 
bourbon, I can't see the difference between 4k and 1080P.

Not to some audio issues. A lot of this falls on the AVR. Mine will 
decode Dobly Digital plus and DTS-HD, but will not pass thru 4k 
59.945hz. When I hook up the Shield to the TV it connects at 4k 
59.945hz. but when I hook up to the AVR It's 4k 30 or 29.9hz. The UHD TV 
can pass the audio back to the AVR via Optical, but only at DTS Surround 
2:5 Neo.  So for me it's a compromise on audio or video or buy all new 
expensive stuff.  Since I own no 4k content, it's not a problem for me.
