Buy the Panasonic ARC5 Electric Razor.

It shaves closer, charges simpler and costs $100 less than the Braun, and the Braun's real edge only matters if you let your beard grow out.

What was compared

1. Closer shave in fewer passes on thick hair
Head to head testing found the Arc5 lifted more hairs per swipe than the Series 9 Pro+, which left rough patches even after going over the same spot again and again. For a daily shaver, that is the whole job done better.
2. Same tier of shave, $100 stays in your pocket
The Arc5 lists at $329.99 against the Series 9 Pro+'s $429.64, and it is not the weaker machine for that gap, it wins the actual shave test. Paying more here buys a fancier dock, not a better face.
3. Charges on any USB-C cable you already own
The Arc5 uses USB-C, so a phone charger or laptop cable tops it up anywhere. The Series 9 Pro+ leans on its proprietary PowerCase dock, which is another thing to pack and another thing to lose on a trip.
4. Keeps its edge, owners say Braun's fades
Long term owners report the Arc5's cutting power has not dropped and irritation stays rare, while one Series 9 Pro+ owner called the performance abysmal after eight months and others flag the head running uncomfortably warm.
5. Yes, Braun bends more. Skip it if you shave daily.
The Series 9 Pro+'s flexible 10D head genuinely helps on long, curly growth, and its SmartCare station cleans itself, but that means buying cleaning cartridges over time. If you let your beard grow out between shaves that flex earns its keep, but most daily shavers never grow the hair long enough to need it.
