Will the Ublox GPS get me more satellites locked more often? Is it more shielded from my other RF sources? I've seen it hailed as a great device but I don't see exactly what's better about it. Thanks

Hi,
yesterday I finally had the time to try my new ublox gps. I fly in a zone with a very bad satellite reception (high mountains all around).
What I verified with the ublox vs em406 is that in two flight the plane made 2x each flight 9WP sequence with various altitudes at each waypoint. I was impressed by the precision of the altitude hold.
With the em406 the plane had some difficult to reach the wp an sometimes it missed them at first attempt, say 1 on 3-4 (the plane will then turn around until it reach the radius, 30m in my case).
Yesterday, with the ublox, it missed a wp only two time. I consider 2 wp missed at first attempt on 36 a very satisfactory result.
1hz refresh means 20m error befor it react vs 5m of 4hz refresh.
I consider this a great improvement on this beautiful equipement: very happy to have it (and the great support too).
To be honest I have to say that the plane dives two times; one time it recover itself and continued the sequence, the second I had to recover it manually.
Bad satellite connection?
Bad IR readings?
Both?
*??
Next step I would integrate it with remzibi osd to be able to take videos (so sorry a day has only 24h >;-D).
Wish list:
- speed hold
- be able to set a fixed rtl altitude
I will try to post some empirical data in the next couple of weeks, I have been experimenting with my EM406A and have not been impressed, When I saw the Ublox for sale over the weekend here I jumped on it! So I'm waiting on it to come in. Once I get it I'll try to run some tests using my netbook and an arduino.
Has anyone compared it to the Venus GPS? On paper that one sounds great (10Hz) and less of a pain to integrate. But I havent heard too many real experiences with it.
Actually, to be precise, the uBlox 5 delivers 4Hz in practice. But the accuracy is amazing, from altitude to sat aquisition, and it even works indoors!

The Ublox update rate is 5 Hz vs 1 Hz for the EM406A.
