Yes, for a few of reasons:
- Ease of use; assuming the money you have is en blanco (i.e. from savings abroad/pension/legal job here) it's a lot easier to pay for stuff now that the largest peso bill in circulation is worth less than 5 USD
- You get discounts for paying with debit cards at certain retailers on certain days
- You can pay your ABL, AySA, Edesur/nor, MetroGAS, phone, internet, etc. online via bill pay or with a debit card
- You can buy stuff from Mercadolibre and other online retailers with debit
- Some retailers offer discounts if you pay via bank transfer since they're charged a fee for processing debit/credit cards
- If you have permanent residency and demonstrable income you can get a credit card which comes with perks of it's own
- You can buy USD cash at the solidarity rate which is cheaper than the blue
Hope this helps!
