Did the stylus experience improve between Lenovo x1 yoga 5 and 7 or 8 models?

I am on the market for a used x1 yoga. I need a reliable, portable laptop to attend my small business needs. 8gb ram, 256 SSD and older gen processor will work for my needs. However I would like to sketch my ideas and concepts on the go. There are x1 yoga 4th gens on the market for 300-400. If the stylus wasn't different between older models and newer models, I will go ahead with x1 yoga 4 or 5. Anyone has experience with this?
