RK, this kind of advice is going to be so personal..You will have to decide with your own ears and hands..

To put this in perspective...I own a G70 (by choice.. )

If someone offered me a Tyros2 "free", with the agreement..I had to play my gigs with the Tyros2 exclusively.....I would decline the offer....the truth..

Now wait and you will read the other side's opinions..

I would look real close, but being that you are a ten year fan of Yamaha..most likely you will stay in the Yamaha camp (comfort zone )...

Although do yourself a favor...check out the competition with an open mind...and ask questions...lots of them...
