Which is worse? Blunder or Missed Win?

I was wondering whether getting a blunder was worse than having a missed win.

Also, because a missed win is a blunder, when is a blunder considered a missed win by chess.com?

Correct me if I'm wrong, but getting a missed win is better for your game accuracy than getting a blunder.

I once got a missed win in the first 10 moves of a game

It seems that a missed win can be triggered with just a couple points of fluctuation from the evaluation bar. Is this a mistake?

Yeah. I think it's an error

I'm wondering that too.

A missed win is worse than a blunder because this gives a small chance for a different person to win when you are winning. A blunder is something you an come back from though. you can't really come back from a missed win.

A missed win is a bad blunder then?

Blunder because you lose by blundering. The game can continue if you miss a win.

missed win

A missed win is where you can win or gain a huge material advantage, but you missed it.

A blunder is when you made a move which actively damaged your chances of winning. 

The big difference is that you're still in the game with a missed win. Even if you could have found a faster mate, you still mating. With a blunder, you are done if your opponent noticed. 

Missed win hits deep in the feels man

Let me have a think.

Not a Blissed Win.

I think a missed win is worst because missed win is a good opportunity that you missed like a good position, piece advantage and perhaps even checkmate. 

A missed win does not necessarily mean we missed a check mate. If we had an opportunity to win a piece and we didn't take it, that counts as a missed win. So a missed win could be anything between acquiring a bishop or a knight to the queen or the game itself.
Similarly, a blunder is when we gift our piece(s) to the opponent or a let him take a powerful position on the board.
Hence it depends on each case as to which is worse. If the missed win was to take the queen or a check mate, obviously thats the worse thing to do but if it was just missing out on taking a knight or a bishop and the blunder we are comparing it to is about losing our queen/giving up a powerful position then the blunder is costly. But as noted earlier, games tend to continue after a missed win and usually ends in our loss when we make a blunder.

A Blunder is 100% worse! It means you either gave up a free piece to your opponent or gave a huge enough advantage for them to win the game. On the other hand I have had plenty of "missed wins" especially in blitz, where I still win the game. A missed win means you had an advantageous moment/move in the game you missed that could have possibly ended the game sooner, or even just netted you material.

A blunder is worse as it turns a won position into a lost position, while a missed win just turns a won position into a draw.

Win because if you blunder you get to win here only I would do a blunder then wis a win

But surely some of these missed wins might be the fearsome cyborg engine seeing something way down some line, right. I would say a blunder of leaving some hanging piece is much worse than not seeing some win opportunity many moves ahead.

I think it's the other way around. You can only really recover from a blunder if your opponent misses the opportunity to get back in the game. Missed wins can turn a mate in 6 to, say, +20. Some blunders are worse than missed wins, and vice versa.
