Its all about your cutting style.
If you like turbo chop style (crush through object) like you see on chef programs, then Euro style/geometry knive are for you.
If you fancy more precise thin paper tomato slices (sliding through object) etc, then japanese style knive are better bet.
I am surprised no one mentioned -Tojiro- , best bung for your money and very good starting point into knife fetish.
I bought Tojiro DP (VG10 steel) 21cm chefs, and 12cm pairing knife for £100 or so 2 years ago. I can cut through bones as well as cut paper thin tomatoes at the same time. But hell, one wrong move and your fingers are out!
My wife hates Tojiro, as she doesnt put much of her heart into food preparation so uses different knife for her speed cooking. While myself enjoy theatrical art of fine slicing.
