The TW can easily more fun than the ninja, if you know what to expect out of it. Firstly, the TW's 0-60 time is going to be in the 15+ second range at best rather than 7 seconds. Don't expect any kind of exciting acceleration, the TW is more like a tractor than anything. Top speed is generally 65-70, but don't expect to cruise at those speeds. A realistic cruise would be 50-55, some people will push it harder but personally I think it's too rough on the engine if you're looking for long term reliability. (30-50k miles)
If you can live with that, from there the TW excels in every category. Light, nimble (fun!) handling, excellent traction and of course the ability to literally anywhere you wish to go on and off road. I had the most fun on my TW exploring back roads at no more than 50 mph.
