I like my Wacker(s), Dovo(s) and TI - all for different reasons.
The Wacker has a great feel/balance and I like the overall quality the best. It is also the sexiest.
The Dovo is simple, but a great shaver that gets the finest hairs cut.
The TI I originally hated. Then I honed it on my own, and rounded the square point at the heel - now I love it for the way it shaves and overall feel/balance.
