New Sim Racer Torn Between LMU and iRacing

I’m relatively new to sim racing and built my rig about a month and a half ago. My main goal is to get into racing Hypercars and GT3s. So far, I’ve started with iRacing, focusing on slower cars like the MX-5 and GR86 to learn the fundamentals and develop safe driving habits.

I really enjoy the structured online matchmaking and competitive environment that iRacing offers, but I’ve been hearing a lot of great things about LMU recently. Since I want to focus on just one platform for now, I’d love to hear your thoughts.

Which would you recommend for someone looking to improve and eventually compete in Hypercars/GT3? Any advice or insights would be greatly appreciated!
