What do you use to Edit and Record???

I use OBS Studio for recording which is free, somewhat simple to use and it actually records really well and I edit with iMovie since I'm on a mac. I've been trying to record my commentary separately using Audacity and it does make my iPhone mic sound better but the thing is I'm having some troubles syncing the audacity audio with OBS' in game sound in a way that I have to cut and rearrange them to match the video but it's pretty manageable..
