Standard usability advice is that if you have two links to the same page, they should have the same link text. That is particularly true when the two links are on the same page, but ideally you should aim to be consistent across your whole site. If you have links to the same place that have different link text, this can be confusing for visitors, who think they are going to different pages only to find they're back at the same place they've already been to.
In terms of SEO, if you have multiple links to the same page on a page, search engines will generally only consider the first one. You don't get any extra credit for repeating the link once or twice, and you're unlikely to get a penalty for repeating it more than that unless it looks fishy. If the structure and navigation means that there is a good reason to repeat the same link over and over again, in terms of making the site easier for users, then do that.
