These days, it does not make much sense to use Legacy addresses (1xxx...), even if you can. You should be using at least wrapped segwit legacy compatible addresses (3xxx...), but even better are the most recent segwit native addresses (bc1qxxx...)
Yes, it is good to use native segwit addresses because it has very low fee, 42% to 52% lower than legacy addresses, also still lower than while paying with nested segwit addresses, but that does not change the fact that the soft fork is backward compatible, which I believe is the best to make people decide which address type they prefer. Due to one reason or the other, some people still make use of legacy addresses, like a payment company that make it mandatory for payment, but to be sincere, I still do not know why people haven't make legacy the thing of the past. Also, this does not change the fact that pay-to-taproot will also be cheap in some instances.
