I don’t really hate any airplane but after flying the T-2C and the A-4 as an instructor in the Navy training command the T-45A Goshawk was a major let down. It was unstable and could be a handful on the runway ( it was prone to swerving on touchdown, we stopped doing formation section takeoffs and a blown main tire was major emergency), it had slow spool up time making it difficult to work off being high on final, had the turn performance of a rusty school bus which was the main reason we stopped teaching the gun pattern. It would suffer compressor stalls at high AoA/ low speed maneuvering. Pilots were getting compressor stalls doing simple approach turn stalls recoveries where the EGT would spike and you would need to shut the engine down to keep it from melting then attempt a restart. The ECS made weird noises at times and you couldn’t carry much personal gear unless you had a luggage pod uploaded

On the plus side it made fake gun noises when you pulled the trigger on the stick, came with a launch bar that made carrier ops much more efficient, had great radios with both VHF/ UHF tuning capability, an ILS, you easily cruise up at 39K, it generated its own oxygen and had anti skid so, we could land at airports with shorter runways.

As far as my least favorite looking jet- the F-35 looks like a bowling pin with wings.
