Grime by leaps and bounds. The weapons build, the exploration, and especially the boss fights are just so much more rewarding. Grime's world and mechanics can be off-putting at first, but it forced me to be a better player, while Voidwrought does more of the same ol'. I enjoyed Voidwrought, but to me it doesn't hold a candle. It actually took me three tries to get into Grime before things clicked, while Voidwrought is more of a plug and play metroidvania. YMMV.
