Hi:
We currently have been using P25 digital radios (VHF) for the past 3 years (both digital mode & analog-narrowband mode) for disaster relief efforts, which is what we do full-time.
We started using the Vertex VX-P924 portable & VX-7000 mobile radio. They are awesome! Though we bought some Kenwood TK-5210 portable, and TK-5710 mobiles - and tried them both out for several months, and we like the Kenwood better than the Vertex, but I rate them both equal in audio quality. The Vertex doesn't have caller ID (receive) as well as MDC-1200 PTT ID decode, but has encode (outbound). The Kenwood does have MDC1200 inbound & outbound, as well as you can add in an "alias list" so it shows an alpha tag -vs- jsut the MDC1200 PTT ID number.
So I would highly recommend both - the Vertex & the Kenwood. Below are their websites so you could view the radio specs:
