>>714648158 (OP)Bloodstained has better progression and gameplay variety just due to the fact that it's the (current) most recent Igavania game that incorporates everything from SotN+GBAvanias+DSvanias.
SotN has tertiary factors that still make it a high-tier game (objectively better music, art, graphics, Rondo/CV3 fanservice etc.). But by virtue of being the first "igavania" style game, it's missing some features from the later handheld games that made them more fun/replayable than SotN.
