There is nothing wrong with the SR20/22 as a basic trainer - especially if that’s what you’re going to progress onto once you’re qualified.
Agreed, it can be a handful and requires greater situational awareness as you’re typically covering the ground at a much quicker rate. This places greater emphasis on the quality of instruction and depth of planning but it’s been around now for 20 years so I am sure these are well matured now.
Sometimes, our bag of luck empties quicker than our bag of experience and skill fills! My thoughts are not only with the family of the student, but also with the instructor - truly dreadful for all concerned.
