Cannot speak for the O-235 on a C152 but the O-240 much better than the O-200 on the C150s I flew because you could (usually) get back out of the short strips you could get into with the 40 degree flap down!
Can also vouch for the B&C starter. However, apart from potential parts problems, I suspect that the O-200 is a bit more reliable than the O-240.
And bear in mind that the 150 Aerobat was different in other ways. I understand that the airframe was beefed up for (basic) aerobatics.
