I do have to inject a slight negative here also. If the radio techs didn't do their due diligence on aligning a simulcast system, then you could have issues in the tower overlap regions with distorted audio. But that is not the norm for a well adjusted system.

If a system does have these problems, then the radio manager needs to get on the case of the radio vendor and get them corrected.
I've heard P25 on several systems.All have the same basic audio quality.Many people just get use to it and don't complain anymore.Most PD and FD users initially complain about the audio quality once switched over to P25 and then after finding out that there is nothing that can really be done about it,generally stop complaining.

I'm not basing my observations on scanners or hobby SDR's.

P25 sounds perfectly good on every Motorola radio I/I've owned. If you're basing that observation on a scanner, yes, it can certainly be a mess.
No scanners.P25 radios.Harris/M/A-COM,Thales etc...

Yep,I've noticed the same on several systems using P25 capable radios.It also happens with AMBE+2 vocoders.
