A while ago, sartega also said that cotton was better choice over wool for an all year round suit or something also those lines
Incorrect actually. I said the wool was better for year round but I did mention to someone who asked about wool vs cotton that if he lives in a hot year round environment like Florida, Georgia, etc. that a cotton suit could very well work year round. Considering that my one major suit purchase from Michael Andrews Bespoke was a year round WOOL suit, I don't know why I would suggest to someone to go with cotton. Please read what I write before stating what I did say. I don't mean to sound or be a jerk but in general I don't like anyone saying what I said and then it being incorrect.
If I recall it was someone asking between a few suits from Express. I suggested the cotton only and only if he was in a hot weather climate year round and even then I still suggested to get a lightweight wool for year-round. Cotton is never a better choice for year round, the draping isn't as great, it doesn't hold up as well to year round wear and the fabric depending on the thickness and even then screams, spring and summer.
