MrDux started this correctly...Ford vs Chevy. Obviously, I am biased since I own and love my War Eagle. It is solid as a rock.
Having said that, there is no "best" aluminum boat I believe any of us can recommend. We can certainly express our thoughts on what and why we like about particular make. I believe it is said above. Please consider your budget; how and where you will use it; and, what you want vs what you need. Do you prefer welded or riveted...I prefer welded. Also, please consider do you want a basic flat bottom jon boat or a higher end v-bottom boat that more closely resembles a glass boat with "all the accessories". Basic considerations will help guide you to the correct choice.
Good luck.
