No$GMB for GB/C is much nicer to handle than BGB, as it follows jumps and stuff with a press a button and can have different locations in asm view and memory view. Also, breakpoints can be set via ctrl + b. It has some emulation flaws (timing issues) and the music is always at 100% no matter what you put in the config.
For gba, sometimes vba-h is helpful
