I started with MDZS back in 2019 and up till this year when I finally read TGCF it held the title eof my favorite book for 4 years. It's a bit more smuttier than TGCF but if that is not an issue then i would 100% recommend it!
I also read SVSS and though I wasn't the biggest fan of it, I still enjoyed it and would rathe it a solid 8/10. Some people in MXTX fandom have it as theri favorite so I would give it a try as well though this one is A LOT more smutty xd
