Is there an upside to using this over termux?

I’ve used Free Tax USA in the past, but I wouldn’t say they’re trustworthy. They’re still part of the free file alliance and actively lobby against the IRS creating their own free tool without any restrictions.

There’s support coming for wifi 6 Qualcomm Atheros chips. The images are still in the snapshot/release candidate stage, so not a full release yet, but they are working.
