In the past i used a few different web wallets, alot of the popular ones. They are cool to use, and I do like them, but I don't know how I would feel about huge amounts of coin there, I only ever had a small amount of coin in the online wallets.
Years ago I used Bitcoin Core for my desktop client, and I would like to use it again to see how it feels and all the changes, but my main drive is an SSD with not much space, so I would have to keep the blockchain on my external, which isn't terrible as it is probably 1.5GB, but still alot of downloading to be done.
As of last night I am using Electrum, so far so good, I'm liking it! It certainly is light, won't take anything to run, and I do enjoy the lack of blackchain download. The features are easy to use, and easy to understand as a new Electrum user. The only thing is, I wish I could customize the skin and look of Electrum (this may apply to all desktop wallets,) maybe use a dark theme or different themes, but ofcourse have to be careful that the themes only change the look of things and add no dodgy code or trackers
