Which is better for competitive FPS?

Both are built for FPS. The Viper V3 Pro has the pro pedigree and the much larger review base. The SABRE v2 PRO matches or beats it on paper with 8kHz polling and a 56g shell.

Is the Viper V3 Pro worth three times the price?

Only if you value the proven shape and the 4.9 rating from 1,100 buyers. On specs alone, the SABRE v2 PRO gives you more for less.

Which has better battery life?

Corsair states up to 120 hours over 2.4GHz at 1,000Hz polling. Razer does not state a battery figure in this listing, so the Corsair is the safer claim.

Does the Corsair work wired?

Yes. It supports 2.4GHz, Bluetooth and USB-C wired, and comes with a 1.8m USB-A to USB-C cable. The Viper V3 Pro is listed as wireless only.

Corsair states 56g for the SABRE v2 PRO. Razer calls the Viper V3 Pro ultra-lightweight but gives no figure here.

Which has more buttons?

The Viper V3 Pro has 6 buttons and the SABRE v2 PRO has 5. Both are programmable.
