It's hard to have a fair comparison, and both compilers are also moving targets. I tried to do some comparison in a sibling comment: https://news.ycombinator.com/item?id=37300279

The best is to mention both (as well as GFortran), and users can decide. For LPython (https://lpython.org/) we list all of the about 30 Python compilers at the webpage, but beyond that it's very hard to have a meaningful comparison.
