Of the platforms you mentioned (nexo, celsius, blockfi and crypto.com), I still haven't tried celsius. I'm thinking about it, but having another platform where I need to buy their own token is not such a great incentive.
For this reason I like blockfi, because they have no token of their own.
Nexo has a wider variety of coins available than blockfi, no fees and some of the best exchange rates, most likely. With Nexo coin above 10% of your portfolio, there are great interests too.
Crypto.com has a variety of features. I have mostly used the Visa card for 2% cashback and two features called supercharger and the syndicate (the later only available on its exchange - must join separately for this one), both of them give you bonus or discounted tokens that are listed on crypto.com.
Leave me a link to celsius, in case I decide to join.
