Much as we normally agree on everything I'm sorry, here comes a first.
PPL, IMC and night all on a Traumahawk (even spun one). Never found it tiring, always found it pleasant. I think the best guide is later, when you're flying bigger and better. I'd go back and fly a Tommy tomorrow, but doubt whether I'd drag myself into a 152.
But as others have said - it's just a means to an end. The aircraft doesn't matter, the school does. You need the school that's going to make you the most proficient PPL in the most efficient way with your hard earned cash.
Plenty of time post PPL to worry about aircraft types and what you're going to play with next
