GPS results with Mediatek vs GS407

Today i've tried a new X4 (3.2.584 and GPS with mediatek module) and the PH seems less accurate than what i've had before with same craft but with 3.2.560 and GS407 module.
First of all it takes longer to get a green fix with the mediatek; in the exact same place and blue sky without any cloud i only get a green led with mediatek and always a blue one with GS407 (obviously it was not at the same time...)
PH looks less accurate with mediatek and also RH was really less good.
Could that be temporary worst conditions from GPS system ? someone already
got about the same results?

The GS407 has a better antenna but it’s a lot more expensive and much more fragile than the mediatek.

I just got my mediatek GPS, I also have two GS407. One that worked very well with very fast blue fix and I crashed and it broke, the second GS407 that I got I couldn't make it work at U-center the ublox GPS software. So no Hoverfly GPS fix.

Now I got a Mediatek and can get a FIX very fast too, blue light in under a minute here. Clear sky.

In MiniGPS software I'm able to get a fix with 6 sats inside my room and 11 sats outside doors, and the fix is very fast too. I can tell the GS407 was faster, but not by a large margin.
