Well, obviously it depends on what you want to use the lines for. If it's just to fade something in or out over 10-50 ms to avoid a discontinuity, it's not that big a deal. Moreover sometimes it's great to have the ends and beginnings of ramps happen at block boundaries; e.g. when [switch~]ing off a subpatch or abstraction in a synth bank at the end of a quick fade, it's nice to know that you can target things to boundaries without having to try too hard.

Hi Frank, The [1, 0 50( message will almost always trigger different output when fed to [line~] and [vline~]. The only exception is when the ramp ends exactly on a block boundary-- otherwise [line~] will stretch the final part of the ramp to the block boundary.
In fact, I'm willing to bet that if visualized this [line~] quantization to new users at the outset they'd almost always use [vline~]. After all, who wants imperfect lines? :)

In that case, maybe an even simpler question:
What is the difference between sending a [1, 0 50( message to vline as opposed to line ?
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~]
