Had the SunRace MX3 (11s, 11t-42t) for almost a year and now changed for MX8 (11s, 11t-46t). Coupled with 29" wheels and 30t in the front the 30-42 ratio was quite hard for steep climbs, but for 650b or 26" wheels it's okay. The MX3 includes shifting gears while backpedalling and slow downshifting, but paid around 50€ back then, which is far away from any other cassette with this range. Recently paid 60€ for the updated MX8, which gave me better range and also fixed my only 2 complaints. Running great with GX/XX1 rear mech and simple SRAM steel NW chainring.
