The Tamiya Tiger is a good tank. Also there is an argument to be made that building a Tamiya kit as a first project sets you up for success as you progress forward in this hobby. When you have to build then you become aware and understand the components. The skill and experience learned here can then be transferred to other kit bashes or whatever else you want to do. A lot will depend on how much RC and modeling experience you are bringing in with you.
