It's quite hard to compare these things. I've been working with Dialogic's
stuff for a while now
and it works quite ok. But you still have a lot of problems if you're going
deeper into their API.
We are building IVR only application's. But these are a bit more complex
than standard app's
and we've quite long call times...
We try to switch to asterisk now. I am preparing a Quad PIII 850 Xeon
Machine with a TE410P
setup and 1 E1 Line at first. Then let's see how much it can handle ;)

If you're asking why Dialogic cards take less CPU look at the board itself
and look at the price!
An Dual E1 Dialogic Board costs around 10k € ! And if you want to do some
conferencing you
have to buy an Dialogics Conferencing Board (there's no other possibility
with more than 2 callers conferencing) which costs around another 10k - 15k
€ !
so if you buy a TE410P instead or 2 of them you can buy a lot more of
processing power.
and even more servers! So perhaps it would be better to distribute your app
to several * servers and you still would be a lot cheaper than using
dialogics hardware...

mho.
