Of course Icom are better than Baofeng, you're paying £25 for a UV-5R which is a dual band handheld compared to £350-£400 for an Icom equivalent.
However, do not buy a Baofeng. They're not type approved for PMR446, they run ten times more power than you're legally allowed to run. They're not utter rubbish as said above but they're built to a price and they're not designed for the usage you're suggesting. Yes, many thousands have been sold to amateur radio operators (I have two) and they're perfectly acceptable as a cheap, throwaway unit providing the owner is aware of that. For my use (and most other radio amateurs), as a wireless to access the local repeater, they're fine.

But they're not legal for PMR, not even close to it.
The Motorola XT420 mentioned earlier is a good choice.
