Damn i thought it was Blaze asking lol
Vps - Virtual Private Server, where you host these tools. ( Unix/Windows )
Sborg - Advance version of phpuploader,
RL - Rapidleech
Rdp - Just think of it as Windows, but its super fast at uploading and downloading,
to compare them, it's like comparing apples and oranges. each tool has it's own advantages and disadvantages.
So there is no perfect answer to which is best at uploading,
You must know you own uploading style, then you choose which tool fits your style.
or you can develop your own tool to suit your style.
The norm,
Sborg - Leeching, automation, speed can sucks at times (single connection)
RDP - not much automation, manual task, speed is good if you use Zoom and IDM
RL? errr,,, cheap, good for just transloading from servers to servers.
