Hey y'all , so I am currently learning about cloudflare because vercel can be expensive , so I have considered 2,3 scenarios for comparison , like first one when the whole next app is static and some images are present , now both cf and vercel charge for image optimization , so which one would be better as both have good cdn but dx of vercel is better , and in second scenario where our app is dynamic,I think opennext adapter would work fine , which one do y'all use btw ?
