At this rate, I think XRP is more recommended for you since it has more liquidity and usability in terms of payment also its developers are strong enough to win every bad accusations against them which lead to their coin surviving until now and it's one of the top currently.
Therefore, if you want to invest in the long term, you can always choose XRP because they have high chance of survivability and have some major influence in the crypto market.
Recently, there was news circulating on the Internet about BRICS countries planning to make use of XRP as part of their payment system for InterCounrty trade and I think one of the major factors the coin has bounced back on track is that they won the lawsuit against them by SEC and it gave people more confidence to invest in the coin. So I will slightly tithe towards XRP.
Doge on the other hand has been a very disappointing coin even during the bull run period and not many stories about it aside from the Elon Musk tweet about it on the 17th of July 2020 that gave it a one-time wave.
