Good question...

>Personally, I bought it mostly to try it out.
From what I know, thick blades have the following advantages over thin blades with a bow:
1) More cutting area since they are not bowed
2) Because of #1 more time between sharpenings
3) Less chance for chatter since it's thicker
4) (pure speculation) More time between sharpenings because the blade is thicker
5) No washboard effect since the blade cuts square unlike the bowed thin blade that leaves dish tracks.
However there are some disadvantages:
1) Harder to start the cut (I noticed that when comparing to the thin blade)
2) Leaves tracks as the corners dig in. This can be alleviated some since the corners can be rounded but there is still some digging.
3) Difficult to adjust initially to the proper depth.
Gene, I can't give you much advice as to whether or not the thick blade is much better than the thin blade. I know that they both performed well. Someone else might be able to provide more info on thick vs thin blades.
I would suggest that you try out the curved blade, see how you like it. You may never need another, and as such, not waste your money since you will be satisfied.
Enjoy your tool!
I am pretty sure you that with some practice and patience you will enjoy using it and good nice results.
I know I did.
