DT Swiss EXC 150 2008 20mm vs Rock Shox Revelation 426 Air U-Turn 20mm

[disintegrator]

I'm looking for a new fork to replace my nearly dead FOX TALAS RLC

I miss the 20mm axle, so I'm going back
Right now I have those 2 forks in sight

DT Swiss EXC 150 2008 IS Mount - 150mm Black - 20mm Axle

Rock Shox Revelation 426 Air U-Turn 20mm - Pushloc 2009 110-140mm Silver - IS Mount

If anyone tried both. Can you tell me:
Which one is stiffer?
Which one will require less maintenance?
Which one has the best small bump compliance?

I'm riding always on loose dirt. The main tubes always get very muddy and the dirt tend to get inside the fork. That's why I'm asking about the maintenance.
BTW, my wheels are Easton Havoc

PS: sorry for my horrible English. It's not my natural language.

I know very little about the EXC, but this year's bolt through Revelations are essentially the same as last year's air sprung Pikes, they have a slightly different Maxle but use the same lowers, steerer, damper etc (the 'all new' Rev comes out next year).

Purely based on that the Revelations will be easy to maintain and very stiff, they'd probably be cheaper to get spares for than the EXC.

Here is a MTBR user's (I have forgotten his username) impression of the DT Swiss fork:

For pure bling, I would go the DT, but have you also looked at the Magura Wotan:

Really any of those forks would do the trick, it's a shame the 09 DT is 15mm not 20mm.

The wotan is very nice, but too heavy. I'm trying to get a low weight in this build

rs forks are easy to maintain. no weird pressure chambers or special tools. like 1/10th the amount of seals in a talas. if you've serviced a fork before, you can service (basic oil change) an RS fork in 15-20 minutes.
