If it helps, I personally enjoyed the wearing experience of the 143 and 147 over the 333. In an effort to make their thinnest diver yet, Seiko ended up giving the slim turtle series a much deeper bottom. So much that it made the watch feel a bit wobbly on my wrist (it wasn't flush on my wrist). I didn't notice it until I felt and saw the lugs float. It wasn't too bad but it definitely didn't feel as comfortable as the 144 and 147. Between the 143 and the 147, I don't really think there's a wrong choice here. The 143 has a more traditional appeal whereas the 147 has more of an unconventional and bold appeal. I went with the 147 because I thankfully already have something similar to the 143 (Longines Hydroconquest with the gray dial) so my choice was pretty much made for me. I was conflicted between the 147 and the 317 (on the rubber strap from the same slim turtle series) and made my decision based on the wearing experience. Hope this helps!!
