The Tamron 150-600 or Sigma 150-500 are very close in price and provide you with a lot more reach. And they will likely produce sharper images across the range due to being much lower zoom ratio.
Once you get involved in shooting wildlife, you will almost surely also shoot birds. For one thing, they are typically more readily available. Secondly, it is very challenging. And with birds, you definitely need as long glass as you can get.
But my first and probably best bit of advice is to get something and get out and shoot. Life is short.
