It really depends...
• Personal perception of a tracker's worth/value
• The attitudes of a particular tracker
• How much bonus seed points I get
• A tracker's formula for how much bonus points I get, in relation to the average size of each torrent
• Etc.
Honestly, these days, the staff of many trackers across the board posses horrific bedside manner. Depending on the tracker, I may not donate to be a "VIP," but I have donated for unlimited downloads with no H&R. That's more valuable to me that becoming VIP. I'd rather pay do download that accept many of their bullshit.
getting a seedbox and VIP is two entirely separate issue. Why would you even use them in the same sentence?
