Should I buy 5.0 or 5.5?

[Hotei]

I've decided to buy Filemaker for my company (7 Macs), and am looking for the most solid and stable version. Would people reccomend that I buy v5.0, or v5.5 (I've found both available for purchase online).

Many thanks,

bill

If price is equal, might as well go for the v5.5
