During robotics season, I carry a multimeter in my backpack and as much as I love the UNI-T meters, weight and size start to matter when you carry something all the time so I wanted a smaller, lighter multimeter that still offered full functionality.  In my car, I keep an old Triplett 2030-C which has served me well over many years; the Aneng AN8203 is a knock-off that can be had for under $10 on AliExpress; both have frequency and duty cycle measurement (important for looking at PWM signals in robotics) along with the standard voltage/resistance/continuity and capacitance…but the Aneng has no current measurement where the Triplett does (however the scale isn’t useful for robotics).
