Stablecoins on defi

I've got a nice chunk of USDC that I wont have access to for a while maybe as long as 2 or 3 years. Would you keep DAI, SUSD, USDC or USDT and what DeFi would you put it on AAVE or yearn.finance or curve.finance? Or do you think splitting it USDC/DAI 50/50 and putting it on a Uniswap pool for collecting some fees with the possibility of some airdrops down the road.

My comfort level is telling me USDC on AAVE and just leave it, until I return.
