DEFI proved to cover many scam projects since anybody can launch it. It is still new but it will settle probably in 6 months from now, and it will be like in small coins masternode world, less than 5% of those DEFI projects will survive to be profitable, but they cannot sustain to offer high APY% rates since there is no institutional liquidity backup like in CEFI.
In CEFI it is all currently defined, celsius is best, nexo is worst (at this point)

I would NEVER put all my assets to CEFI, since in that case i lose all my coins if CEFI platform fails. But i trust them more than DEFI since currently most of DEFI projects are gamble. Those which are defined good, like AAVE , offer very low interest rates. At time i write this, Interest APY% on USDT is 4.38% at AAVE, 10.51-13.86% at Celsius and 11.79-14.17% at Apyharvest. On ETH is much worse - AAVE APY% on ETH is 0.11%, at Celsius is 5.5-7.21% and at Apyharvest 6.25-7.82.
My current portfolio is 50% staking in CEFI, 50% i keep at cold storage ( and o still buy crypto on be-weekly basis)
From I stake ETH at Celsius, and Bitcoin, USDC and SNX at Apyharvest. I have also Crypto com atm card, and it is pretty usable, only thing i hate is that CRO coin is losing value, so i overpaid my initial card deposit when i started long ago.
I started at crypto com on July 2019, on Celsius on December 2019 and on Apyharvest on April 2020.
Hope you find my inputs informative.
