If you want "hard to land" then it is the Pitts or the mid wing Extra 300, but that is not what this thread is about.
The PA38 rewards good technique from the tyro and is the best of the American trainners of it,s age but the 13,000 hour spar life has resulted in the high time aircraft becoming very "under loved" by owners who won't spend any more money on an aircraft that is soon to be scrap.
I wanted to run a business with two PA38's but the numbers did not stack up due to the spar life issue an had to settle for two Cessna 152's as it was worth investing in aircraft with no restriction on spar life to get them to a standard that I would be happy to lease out.
