other people beat me to it...

Question being " OUT OF THE BOX RUNNER" A tamiya isn't runnin anywhere outta the box..lol

Some people either don't want to or don't have the time to build the Tamiya. And then factor in the radio, battery and charger costs to operate it..
That Sherman that costs 490 is now 650 to run it..

A Taigen... you open box, remove tank and accessories, charge battery, install AA batts into radio and then head for the hills...
And the full metal versions with all the asiatam upgrades already installed is a bargain! I did all the research when I got mine.

I would buy another Taigen in a heartbeat.
