Less power in the Cont. O-200 C150 vs the Lyc. O-235 C152 ie 100hp vs 110hp. MTOW 727kg vs 752kg (or thereabouts. It's been 10yrs since I last operated them).
The aerobat is slightly heavier than the non-aero model (~20kg?). Quite a few extra rivets in it and, I think, some thicker aluminium. It has skylights in the roof (optional on the standard models), 4 point harnesses, removable seat cushions to allow for flat pack parachutes and quick-release door hinge pins. The aerobat also has an aerobatic approved engine
The standard C150/152 can operate in Utility category ie +4.4/-1.76g. It's approved for intentional spins.
The aerobat model is certified in the aerobatic category @ +6/-3 g. It's approved for spins, loops, rolls (aileron, barrel & snap), stall turns and combinations of these. Some of the limiting speeds are different eg Vne & Vno.
They're my favourite basic trainer.
Forgot to add
Like many Cessna singles they're all equipped with Cessna's 'Land-o-matic' (tm) undercarriage
& 'Omni-vision' (tm) rear window
. Their 'Nav-o-matic' (tm] autopilot is a possible option.
