I actually don't understand what people love about BC. The only thing I find it extremely useful for is the occasional files where inline diffs are practically mandatory, like CSVs. Other than that, I generally find it frustrating compared to TortoiseGitMerge, except perhaps for some very specific/unusual scenarios. In particular the line highlighting is annoying - instead of coloring the lines that were added vs. removed differently, it colors lines according to whether they're an "important difference" or "unimportant difference" (?!), which is borderline useless to me. What do people love about it so much?
