Quite a lot of questions concern the difference between two specified words (often with an example sentence, where OP wants to know which to use).
It's much easier to search for an existing Question about some given word-pair if you know the format that question is likely to be in. I personally would prefer the 'minimalist'...
word1 vs word2
...and I don't really care whether Vs is capitalised or followed by a period, since that doesn't affect searching.
