Doug -
I've used both the standard and warmtone versions of Fineprint VC. Most recently, I've been using Sprint developer, but I also used Ilford Multigrade.
In general, I find that both the standard and warmtone versions of Fineprint are both colder and contrastier than Multigrade IV. It responds well to filtration, and it is distinctly more responsive to selenium toning that Multigrade.
The choice between brands of filters should mainly be based on what can you get. The one rule to follow is to never mix brands. The actual contrast that you get with a filter of a specific number may not match between brands, but that's not important. What is important is that you get a variation in contrast as you change filters within a brand.
As Thomas pointed out, the first reaction to Kentmere is that it is very contrasty and very cold. But once you calibrate yourself to its contrast range (you will find that the 00 through 1 filters will get a lot more use), it can result in some very 'zingy' prints.
