Which aircraft was surprisingly fun to fly to grind out your end goal?

I’ve been playing for a while and decided to grind out the Rafale. The mirage iiic has been surprisingly fun to play and has been my go to for grinding out rank the following mirages on aircraft and even other branches in the tree. Matchmaking is decent. Even on an up tier I don’t have to face a swarm of radar missiles and I can survive most battles with multiple kills. Albeit, I have to rearm and refuel at least once 😂.

What’s one aircraft you enjoy?
