Just went through the same due diligence process; I actually started looking at Tracker aluminum due to financial outlay concerns and it was my first "new" boat purchase. I was weighing the Tracker and also the Nitro Z6. I really liked the layout of the Nitro and if I was a bit less timid, I might have selected that. That said, in my due diligence process I learned about the Ranger Aluminum Tournament series boats. I learned that the Tracker boat was not as well built as the Ranger RT178/RT188. I like not having to deal with any plywood in the deck that could delaminate over time and liked the idea of having the foam injected throughout the boat. Also didn't care for the cheap steering wheel on the Tracker. I went with the RT178 series boat. I elected to go with it because it's a better built boat for the money. I did not go with the Ranger glass boat simply because it's more expensive for what I want and willing to pay for and as I previously mentioned, since this is my first "new" boat and to a great degree my first serious fishing boat, I felt I ease into boat ownership with an aluminum boat that won't sink and one that is a bit more forgiving should I run up on objects. If you did go with a Nitro Z6, do get the HAMBY keel guard. Keelguard did purchase HAMBY but the one ordered at the factory is the stick-on type, not the one put on at the dealership. The HAMBY installation process uses a bonded fiberglass epoxy so it won't peel on you and it's significantly thicker. Also, another piece of news, BassPro purchased the holding company that owns Ranger Aluminum boats and Triton boats; not sure about the Ranger glass boats.
