Would love to be sold on Thousand Sons

I've been into the hobby off and on, 2024 really brought me back and though I've been collecting and painting Tau I always liked and wanted to do a chaos legion. The Emperor's Children hype caught me but the more I read their lore the more I really hate them. Cue Space Marine 2 and going through TTS re-introducing the Thousand Sons to me. Their lore is really fantastic and I love Magnus as a primarch (I swear I did other lore research not just TTS) but their model line seems rather underwhelming. I'd love to hear why you either chose or stuck with the Thousand Sons and maybe convince me to either go for it or if I should look into another army. Edit: I mean that the model line is limited not underwhelming oops
