I have an '04 Stumpjumper Comp and truthfully I would have to say its the best handling hardtail I've ever ridden. The Fox F80x up front alone makes it leaps above most other bikes. The ride is more forgiving than I expected of a 3lbs aluminum frame as well. The '05 comes disc break ready with a 3x front wheel, which takes care of my only two complaints of the bike. The radially laced front SUCKS but thats not an issue anymore. I'm still always amazed how the bike climbs. Any of the bikes you mentioned though would be good choices. The Kona's geometry is a bit more relaxed as I recall. Its all what you are looking for.
