Who wins each row, and why

Typing feel & switches: MX Mechanical (8.5 vs 7.5)

This row decides the result. The MX Mechanical uses low-profile mechanical switches, sold in Linear, Tactile Quiet and Clicky versions. The MX Keys S uses scissor keys with dished keycaps, which feel like a very good laptop keyboard. Neither is hot-swappable.

Gaming performance: MX Mechanical (5.5 vs 4.5)

Both are office keyboards, so both rate low. Logitech does not publish a polling rate for either. The mechanical switches earn the MX Mechanical one extra point. Gamers should look at our best gaming keyboard list.

Build quality: tie (8.5 vs 8.5)

Both are full-size boards from the same MX family, at 828 g and 810 g. Nothing in the official specs separates them.

Ergonomics & layout: MX Keys S (8 vs 8.5)

The MX Keys S is 20.5 mm tall against 26.10 mm for the MX Mechanical, so your wrists sit lower. Neither has a palm rest in the box. If you want a compact version, Logitech sells the MX Mechanical Mini and MX Keys Mini.

Connectivity & battery: tie (9 vs 9)

Both connect over Bluetooth or the Logi Bolt receiver, switch between three devices and charge over USB-C with a 1,500 mAh battery. Logitech quotes longer battery life for the MX Mechanical: up to 15 days with the backlight on and 10 months off, against 10 days and 5 months for the MX Keys S.

Software & features: tie (9 vs 9)

Both use Logi Options+ for custom keys. Logitech lists Smart Actions for the MX Keys S, and describes its backlight as proximity and ambient-light sensing; the MX Mechanical gets "smart backlighting".

India value: MX Keys S (7 vs 7.5)

The MX Keys S costs ₹596 less on Flipkart. Both carry a 1-year domestic warranty per their Flipkart listings. Add its lead on ergonomics, which carries 35 points in the Ergonomic profile, and the two tie there at 81, with the Keys S half a point ahead before rounding.

What does the extra money buy?

Paying ₹596 more for the MX Mechanical gets you mechanical switches, a choice of three switch feels and twice the rated battery life with the backlight off. It does not get you a better build rating, more devices, more software features or a longer warranty. You also give up 5.6 mm of height, which matters if you type without a palm rest.

If neither full-size board fits your desk, the MX Mechanical Mini and MX Keys Mini drop the numpad. Our best wireless keyboard list scores all four.

Which should you buy?

• Writers and coders who type all day: MX Mechanical. Pick the Tactile Quiet version if you share a room.

• Shared offices and frequent video calls: MX Keys S. Scissor keys are the quieter choice.

• Laptop users who like flat keys: MX Keys S. It is slimmer and feels closest to a laptop.

• Anyone who hates charging: MX Mechanical, rated up to 10 months with the backlight off.

• Tight budget: MX Keys S, ₹596 cheaper. Or see the best wireless keyboard list for boards under ₹5,000.

• Gamers: neither. See the best keyboard in India guide.

Checklist

• Confirm the switch version on the MX Mechanical listing: Linear, Tactile Quiet or Clicky.

• Confirm the Logi Bolt receiver is in the box; some regions sell it separately.

• Check OS support for your computer on Logitech's product page.

• Recheck the price on the day you buy; a second MX Keys S listing on Flipkart showed ₹9,995.

• Buy from an authorised seller so the Logitech India warranty applies, and keep the GST invoice.

Common Mistakes to Avoid

• Assuming "mechanical" means loud. The MX Mechanical comes in a Tactile Quiet version.

• Expecting hot-swap. Neither keyboard lets you change switches.

• Trusting the MRP. Both sold for far below their listed MRPs; compare selling prices.

• Expecting a gaming keyboard. Both rate 5.5 or lower on gaming performance.
