grbl is best compared to the "Marlin" software that drives most 3D printers. Both are very different from LCNC. Marlin and grbl are really similar in many ways. 1) Marlin and grbl both run on Arduino, even the low-end "Uno". 2) They are VERY efficient because the configuration is done in the dot.h file and then the system is recompiled. 3) grbl only drives 3-axis machines that use stepper motors 4) like Marlin, but unlike LCNC, software stepping is very accurate and fast. Because both grbl and Marlin run on bare metal with no OS. 5) grbl has only the most primitive user interface -- code letters you type into a serial terminal, no screen of any kind. However this s a feature, any GUI would have to be done on a PC in a completely separate program.
The main limitation is (1) stepper motors only and (2) three-axis only. One huge advantage over LCNC is there is zero learning curve and nothing to configure because there are no config files.
