Jaxx sucks a lot. The older desktop versions were as slow as hell, my wallet froze constantly when I tried to scynch it, the newer version is a little bit better but still takes ages to sync.

You would expect to sync instantly like Myetherwallet, not sit and wait there 5 minutes. It's just a horrible experience for me.

The browser extension is nothing better, I had a hard time figuring out how to use it.

My experience with it was awful.
