Pros and cons of vector search in elastic?

I'm comparing Elastic vs other pure vector databases vs Mongodb/redis offerings. Is anything wrong or supplemental? Thank you!

Pros: - It's an Elastic product, meaning high SLA and needless to buy other products when doing business with Elastic. - Have built-in Embedding models: ELSER. - Hybrid search with text+vector - Security

Cons: - [Doesn't support quantization](https://discuss.elastic.co/t/about-the-dense-vector-compression/319398), which may be too exhaustive when storing vast numbers of vectors. - [Performance seems poor](https://ann-benchmarks.com/) - Does not support CUDA/GPU, versus milvus support Nvidia RAPIDS
