When it comes to electric razors, two models that stand out from the rest are the Braun Series 9 9370cc and the Panasonic Arc5 ES-LV65. Both of these high-end shavers are designed to provide a close and comfortable shave, but they have some key differences that set them apart.

First, let's look at the design and build quality of both models. The Braun Series 9 9370cc has a sleek and ergonomic design that fits comfortably in the hand. It has a stainless steel body with a silver and black color scheme, giving it a premium look and feel. The Panasonic Arc5 ES-LV65, on the other hand, has a slightly more angular design with a black and silver color scheme. While both models are well-built, the Braun Series 9 9370cc feels slightly more solid in the hand.

In terms of shaving performance, both electric razors are excellent. The Braun Series 9 9370cc uses a unique SyncroSonic technology that allows it to adjust to different beard types and densities. This results in a very close shave with minimal irritation. The Panasonic Arc5 ES-LV65, on the other hand, uses a five-blade system that is designed to capture and cut even the thickest of beards. While both models provide a close shave, the Braun Series 9 9370cc seems to handle thicker beards slightly better.

Another key difference between the two models is their shaving heads. The Braun Series 9 9370cc has a flexible shaving head that can pivot and adjust to different angles, allowing for a more comfortable shave in hard-to-reach areas. The Panasonic Arc5 ES-LV65, on the other hand, has a fixed shaving head with a unique "Active Shave" technology that helps to lift and cut hairs. While both systems work well, the Braun Series 9 9370cc's flexible shaving head seems to provide a slightly more comfortable shave.

In terms of features, both electric razors have a range of options to choose from. The Braun Series 9 9370cc comes with a cleaning station that uses an alcohol-based solution to clean and sanitize the shaver. It also has a travel lock and a LED display that shows the battery level and other important information. The Panasonic Arc5 ES-LV65, on the other hand, comes with a pop-up trimmer for trimming sideburns and mustaches, as well as a cleaning mode that uses sonic vibrations to remove hair and debris from the shaver.

Finally, let's look at the price of both models. The Braun Series 9 9370cc is generally priced around $200-$250, while the Panasonic Arc5 ES-LV65 is priced around $150-$200. While both electric razors are expensive, the Panasonic Arc5 ES-LV65 seems to offer slightly better value for money.

In conclusion, both the Braun Series 9 9370cc and the Panasonic Arc5 ES-LV65 are excellent electric razors that provide a close and comfortable shave. While they have some key differences in terms of design, shaving performance, and features, both models are well-suited to different types of users. If you're looking for a premium shaver with advanced features and a comfortable shave, the Braun Series 9 9370cc may be the better choice. However, if you're on a budget and want a high-quality shaver with excellent value for money, the Panasonic Arc5 ES-LV65 is definitely worth considering.
