I switched for the first time last year after using Windows exclusively for the past ~30 years, and have had no issues whatsoever. I understand I might be an outlier in that I always had a compulsion to dig as deep as possible into my Windows install to change little things I didn’t like about it, so maybe I just already had the base knowledge to more easily switch.

But I’ve been using EndeavourOS, and it’s been an absolute joy.
