I have repeated several times, also elsewhere, that I personally consider Dai and its MakerDao ecosystem the best of the Stablecoin releases in the last 2 years; but this does not mean that it is 100% reliable and I would not recommend putting all your savings into one stable, but it is always preferable to divide on more coins.
What are your thoughts about EURS?
I am not sure you can compare USDT where you are not aware of whether they are backed by fiat USD; and EURS where they upload daily statements and have audits from BDO.
