I am leaning more towards XRP purely for the better possible returns. I do believe Bitcoin is here to stay but less than a 4X from current price doesn’t appeal to me.
Go check other shitcoins, you will see many shitcoins will offer better possible returns than XRP and it will never end.
Again it's up to your decision, if you're only looking to get rich quick, you can choose shitcoins. Don't cry if your shitcoins will worth zero because it has a high chance to become a dead coin than multiply your investment.
Bitcoin is good to store your wealth, not get rich quick, you will a good return after hold it for many many years.
