If I am to decide which altcoin I will preferred to be paid with, I will choose ethereum because this coin is easy to use and can be easily converted into fiat or any other crypto, this is also the second best coin in crypto, it is reliable, faster in transactions and with low fees, and will yield big profit when hold on long term.
Ethereum is by far the best choice if you want to be paid with altcoins, and there are many reasons for that, first of all is the coin with the highest market capitalization and even if it is not accepted in as many places as bitcoin most exchanges will accept it and you can convert it to bitcoin or to fiat, or even better you can keep that ethereum and keep holding it because it is also an incredible investment.
