Even doing it randomly, I found the content is extremely heavy on "play the most forcing move, ideally sacrificing the strongest piece possible with check". It took me 10+ problems to find one where this didn't apply (#659).

This would go down well on Reddit, where that style of puzzle is almost the only one appreciated. And it's a good way to quickly drill a few checkmate themes. But for chess improvement I would recommend a more general tactics trainer. IMO Chesstempo cracked the problem of automatically generating and rating interesting problems, but if you find the interface there too dated, lichess or chess.com have a reasonable second-best.
