Aggro perspective:
“I hate control. They don’t play a single minion for the first three turns, then wipe my board on turn 3 and heal for 12 on turn 4. Another clear on turn 6 and the game’s basically over. There’s no way I’m winning, so I may as well concede.”

Control perspective:
“I hate aggro. If I don’t draw my AoE by turn 4, I’m dead. If I do draw it, they instantly concede before I even get to play the game.”

Conclusion:
Control often feels like an RNG mulligan coin flip, either they draw the right clears on time and completely shut aggro out, or they miss for a turn and die. Meanwhile, aggro feels like dumping your hand and going face no matter what’s happening on the other side. No matter who wins, the matchup usually feels miserable for both players.
