Soyuz 2.1a vs Electron
The Soyuz 2.1a and Rocket Lab's Electron represent two eras of small-to-medium lift. Soyuz descends from the most-flown rocket family in history — a kerolox design lineage dating to 1957, refined over thousands of launches. Electron is the commercial era's answer: a small, carbon-composite, 3D-printed-engine launcher built for dedicated smallsat rides, now recovering its boosters by parachute.
They rarely compete for the same payload today, but together they show how the reliable-workhorse formula has evolved across sixty years of launch vehicle design.

The short answer
Soyuz is the refined endpoint of 20th-century expendable design; Electron is the small launcher re-imagined for the rideshare era — including partial reuse.
