There will only be a difference in how line~ and vline~ react to this message
when the message was triggered by something with a "clock" inside. These kinds
of messages are called clock-delayed messages.

Clock-delayed messages originate in objects like [metro] or [delay] or [qlist].
Messages that originate for example in mouse clicks are not clock-delayed (i.e.
if you click a [bng] or move a slider). 

vline~ evaluates clock delayed message with high, sub-sample timing accuracy.
line~ quantizes even clock delayed messages to block-boundaries or to 64
samples, I'm not sure ATM which it is. But line~ quantizes.

So depending on when the message was issued any by what, the ramp generators
may act the same or different.

Try delaying the message: 

 [bang(
 |
 [delay 0.3]
 |
 [1. 0 50(
 |
 [line~ or vline~]
 |
 [print~]
