Shouwa Genroku Rakugo Shinjuu

Both being based off of Josei manga, they a similar feel in that the two protagonists have contrasting personalities; one is conformist, straight-faced and ordered while the other is unruly, wild and unconventional. Both sets of protagonists have a strong bond that intertwines with an accompanying third female character, helping to progress the plot as well as their respective relationships. They both have a similar feel and art style to them, and a creative technique (music vs rakugo) is central to both. If you enjoyed Sakamichi, you'll almost definitely like Shouwa just as much, if not more so.

Samurai Champloo

Same director, very different, both extremely enjoyable. Music plays a central role in both of these, with Cowboy Bebop having mostly jazz, blues and rock and roll influences while Samurai Champloo being more hip-hop and chillhop. While they both have quite different settings there is definitely a similar feel about them. Bebop is more deep and complex than Champloo, and thus is something of a step-up or even upgrade from Champloo.
