I've personally been very happy with Exodus, but I'm afraid that it's not fully open source.
Parts of the wallet are open source though and they're transparent about that fact.

https://support.exodus.io/article/89-is-exodus-open-sourceI do want to check out Hodler, since it seems to be fully open source.
Its time to move on closed source wallet like Hodler wallet. We need more of security than nice interface, as Hodlers all we need is the full control over our funds and fully very every aspect of our coins security. I'm also eyeing on Hodler wallet since it's the first and only multiwallet. Seems like they got the point of cryptocurrency which is to give every user the freedom from any third trusted party. I'm in their telegram and the are actually having infrastructure test with Bitcoin airdrop, you should check it out.
