I swapped aircraft a few times during my training. My school insisted on airline type checklists so it didn't really make that much difference.
What was painfully annoying was flying with 7 or 8 different instructors up to CPL. Changing instructors every other flight was much more of a problem than a checklist. Read the list do the actions. Not that difficult.
Remembering all the little ridiculous things my multitude of instructors would insist on me doing was much more stressful.
