There are many different music trackers on the market, but two of the most popular ones are Polyend Tracker and Renoise. They both have their pros and cons, but ultimately it comes down to personal preference. Polyend Tracker is a very lightweight and portable tracker that is easy to use. It has a simple interface and is great for beginners. However, it does not have as many features as Renoise. Deluge is a more advanced tracker that has more features than Polyend Tracker. It is more difficult to use but offers a lot more flexibility for advanced users. The same is pretty much true on a large scale comparing the Polyend Tracker vs Octatrack or Digitakt
