Thanks for sharing this info! The stuff I dislike about these wallets is the amount of storage needed.
Swing wallet (ZENCash Desktop GUI Wallet on Windows): "On first run (only) the wallet will download the cryptographic keys (900MB or so)"
Eleos wallet: " First time installations may take awhile to load since ~1GB of cryptographic data must be downloaded first."
I assume we cannot delete the cryptographic keys after install. Given that, it is a lot of data being stored.
IF you plan to store the Nodes on your own storage i don't really think any of them will let you down load a min usually it's all or none but if you use a online Wallet some have a extention or addon you can down load the wallet i don't store is the ETC wallet i found this
https://www.myetherwallet.com/ it does what mistg or any ETH wallets dopes , without the download ......you store every thing but the big download
the ZEC wallets right now are not to bad to down load and store and usually DL fast . i do keep a updated btc and Ltc wallet on one of my storage drives on this PC .
