Torn between 3 GR.3 cars

Spoiler: I’m a little new to GT7 specifically but I have moderate motorsports knowledge.

Assuming all isn’t an option, which out of these 3 are the overall best when it comes to a mix of solid power/top speed, cornering in slow maps and stability.

• Ferrari 296 GT3
• Porsche 911 RSR (currently own)
• Mercedes AMG GT3

Seen great things about all, but I want a go to GR.3 car that’s my go to. I like the RSR, but it feels underpowered on faster tracks with less chicanes.
