learn to drive in safe setup or aggressive setup?

I have a steering wheel since a month or 5 ago. I’m still 5 seconds off from first place round times in open lobbies. I always drove in safe setup and that allowed me to get a little bit better, albeit slowly. Now with the new DLC I realised I can’t drive most of the new cars since I’m not used to the lower level of TC.

So I switched my gt3 setups to aggressive. Not to be faster per se but to learn how to drive with less TC. I manage barely. I have about 1 mess up per lap so I can rarely finish a race or even set a lap time anymore. Up until the point that I’m getting frustrated. I know how to drive with less TC but it’s a tough learning curve.

My question is: would you recommend switching back to safe preset and have fun or keep struggling with aggressive setups?
