Review (5/5): More shaving surface is better.
After using a Braun, Panasonic, and a Norelco (with only single blades) I thought I would try the new design with 3 blades in each of the three heads.
The best feature of the Braun was the ability to lock the on/off switch when traveling.
I bought the Panasonic because of the Linear motor. It also had the fastest motor speed. It doesn't get slower as the battery drains. I think the motor was actually too fast to get a great shave.
My old single blade Norelco (8894XL) is great. The motor seems too slow at first and the shave takes a little longer, but I liked the results and the way it looks and feels. It was time to replace the blades again, so I decided to go for newer technology.
The new one (9160XL) has more shaving surface and is quieter. It doesn't have a digital readout like my last one, but it can work with a cord if I don't re-charge it in time. It still has that great Norelco feel. I don't think it's any faster, but I get a better shave in the same amount of time. I need to re-charge it about once a month. I checked around for price. Amazon won by $30.
