I'm patiently waiting for the planned database tables [1] (or the similar plugins to mature). However, even if this is implemented correctly, it is still going to be on a page, not block level (query/attribute/two-way links...). That is why I will probably stick with outliners.
Or, I may give Siyuan [2] a second chance. I'm actually referring to this now because they just released 3.0 with those local notion-style DB tables. Think Anytype but with an Obsidian feel, and it works on the block level!
