My thought on the 5 pole was that it would give you some protection but because the skirts were not as steep you could hear someone calling you off frequency better. They would be down but not out. The 5's have slightly less insertion loss and are cheaper. On the other hand they need an offset adjustment and therefore don't lend themselves to diversity reception as well.
I think the answer is: it depends on your style of operating and what you want to spend. The reason there is more than one choice is that one size does not fit all. Or, as my Nana used to say, "that's why they don't make it all vanilla."
