Inbound links from topical, well visited pages, are always the best...you will pick up traffic and better conversions this way...
You also want to consider how your outbound links from your site to other resources are formatted...your site visitors will gain more value if there is continuity and the bots will flow through your site and pick up on this topical continuity...
If the PR8 site is not on your topic and you set an inbound link from them you will certainly want to control the anchor text as much as possible...this way you at least gain the benefit of the correct anchor text link from a PR8 that is off-topic ... you may pick up some visitors as well but I would think your conversions would not be as good as the on-topic PR6 inbound..
Always think visitors first...then you are building for the web first and the bots second...
