I currently have a s8 plus which I have been using since it came out and it's been an amazing tablet over the years. I've been thinking about upgrading and the s11 and 10 seems a bit pricey so I was wondering if the s9 ultra would be a substantial upgrade over the s8 plus. Is is worth it to get the s9 ultra or should I just stick to the s8 plus?
