An Uno Rev3 made by Arduino themselves rather than a budget copy. Same ATmega328P at 16 MHz, 14 digital I/O with 6 PWM and 6 analog inputs, but with the ATmega16U2 USB interface the official design uses - so it enumerates without hunting for a CH340 driver - and the build quality and support that go with a genuine board. Worth the difference for teaching sets, resale, and anything you would rather not debug twice.
Key features
