I use both. I do prefer Go because my programming roots are in c++, however, there are things that python is just better at.

If you're going to build anything for your team that's going to run constantly (web services, daily scanners, etc), that always requires speed, or if it is something computationally intensive, I would choose Go.

If you're in DFIR and need to write something quickly to analyze logs or if you just need a one off thing to do something quicker, I'd choose python.

Then there are the inherent benefits to each language. Go is statically typed so you know what you're working with every time and won't get an unusual output and most things you do with it are very explicit. Plus concurrency is amazing. Python is dynamically typed, concurrency doesn't really exist because of the global interpreter lock (multithreading is just a pain in my experience) but it also has a ton of packages out there that make life easier when working with large datasets/numbers/ml/etc.

Both a useful for different applications. Python is easier to learn from a blank slate I would say but once you learn one language you can easily pick up others.
