For anyone who does a lot of einsum I highly recommend the einx package because the stock single-letter syntax very quickly becomes hard to read.

In your experience, why einx over einops+einsum?

I didn't try einops, just went to einx because the interface seemed cleaner. I do think that some of its more "powerful" features do lead to cryptic expressions once again, so I avoid them.
