Electrum only accepts bitcoin, and one version of electrum only accepts bitcoin cash; whereas Exodus accepts Aragon, Augur, Bitcoin, Dash, Decred, EOS, Ethereum, Gnosis, Golem, Litecoin, and OmiseGO. If you wanted a wallet that can support more, try out
Exodus Eden. Take note, Eden is still in it's alpha stage so expect alot of bugs.
Not sure about the "limits" you're referring to, but I'm pretty sure there are no limits on these wallets, only the transaction fees.
