I think serverless nextjs (https://www.serverless.com/blog/serverless-nextjs) is a game changer. I like pure react apps because I can quickly host them using S3 buckets in AWS. However you can't do SSR. But with serverless-nextjs, the SSR is done using lambda@edge. The deployment is fast and AWS is extremely cheap at low volume use. (Note: Support for multiple environments is not good so you need to do some hacking.)
