Zamorak and Bandos possess a special I do not care

I would like to receive one of those four Godswords. I would use it on RS gold creatures only since I've never pvp'd and don't plan too. My att, str, and def are 85 (for other stats, visit my profile for link). They're all the same rate, right? Are they as fast as a whip? That may bring in around a bit over 10 million. I could get up to a 5 thousand or so selling odds and ends, likely. Armadyl is too expensive.

Zamorak and Bandos possess a special I do not care about (so for me, they are equal), and Zamorak is significantly more expensive, so that out one. Saradomin Godsword includes a useful unique (it works against monsters, right?) , I simply don't know if it is worth the excess amount for it. Bandos is approximately 20 million and Saradomin is around 50 million. Can anybody tell me about the Sara unique? How much of the cheap RuneScape gold bar does this take? Can it be used to get back a fair quantity of health? It says it gets back at 10, but I would presume it would frequently be a bit higher. I'm simply not certain if the 30 million extra is worth it.
