I really don't understand why so many people have so little respect for the Budapest. It's been played by World Champions and still scores reasonably well in correspondence.
I'd be very happy if everyone consigned it forever to the trash heap of history, but just wait... Nakamura or Carlsen will play it in a serious event and it will be treated as the prodigal son returned.
To rank the BDG ahead of the Budapest in terms of soundness? Really? How many GMs have played the BDG compared to the Budapest?
what about the Blackmar-Diemer?
I saw a GM play 2. ... e6 instead of capturing
I would put it above any of the gambits on the list in the OP, but still below theoretically sound (and effective at all levels) gambits like Evans, Lolli, Benko, King's, etc. It's in an inbetweenish group along with the Smith Morra Gambit -- effective and hard to refute below GM level, but never played at GM level.
