It all depends on your application. If your a prerunner, you can get wicked travel for cheap with the TTB. The TTB is esentially a mud plow though.
If your a street queen, and rarely go offroad, the IFS will do fine. Cons of this are parts wearing out more quickly, terrible flex etc.
The D35/44 is for more extreme wheeling. Generally paired with bigger tires. It gives you better and more predictable articulation than an IFS or TTB. Cons are pretty much nothing beyond price.
