I just went through this same search for the same two implements. I am really happy with my purchases.
Here's a thread I made with my own concerns.

The titan forks from palletforks . com are great, free shipping, can't complain. My loader is nowhere near strong enough to lift a fully loaded pallet of good with them, though. As LD1 pointed out. They are great for brush, smaller logs, lumber, etc.
And for a toothbar, I went with an iowa farms one from ebay.
As an owner of a ratchet rake, let me give you the direct comparison with a tooth bar: yes, the ratchet rake is a little better at clearing virgin brush. But that's it. I see a lot of people on this site exclaiming about how amazing their ratchet rake is, and saying that people should get one over a tooth bar. They simply don't compare. A ratchet rake PREVENTS you from being able to dig dirt. The only thing it can do is scrape along the ground. And if you get a bunch of brush cleared with it and try to push it around, you're going to damage the ratchet mechanism and the straps that hold it on. Ask me how I know this.
With a tooth bar, you can get brush and roots out of the ground almost as easily (in some ways even better, as you can DIG underneath things), but you can also still smoothly backdrag, and of course still USE your bucket for scooping and carrying stuff around (which you can't do with a ratchet rake, since the straps are in the way).
The digging power of your FEL more than doubles with a good tooth bar. Almost dangerous... you can get too aggressive and over work your loader and tractor. Be careful!
