I like my Swoe as you can also use it vertically if weeds are up close to - say - leeks, but that oscillating hoe looks pretty impressive too!
I had a cheap B and Q version some years ago, but the blade was far too thin and broke after a couple of years, but both designs are much better than the original Dutch hoe design!
I bought a Darlac DP2581 Narrow Spade Hoe Long Handle UK a few years ago, and this is more accurate than any hoe, and also very sharp, but takes a while to cover a large area as the blade is so narrow!
