but leafleech was hacking accounts and is a scam, check wj..Leafleech is better.
Sparkling just lost its touch. They have a bunch of premium accounts and I was actually testing them one day and a good amount of them didn't even work (8). Their ul.to plugin is always giving me problems. They had 2-3 days of downtime as well and when I contacted support about this, they weren't very friendly about this.
I'd suggest you test their demo since leafleech is mostly EU servers and sparklinghost offers US servers.
