For ordinary radio and TV mending any DMM will be more than accurate enough. It's down to features and robustness. Sometimes an analogue meter will be better. The 2 examples I can think of are when the swing of the needle gives you useful information in a way that digits can't. Many DMMs have a bargraph scale that can replicate this capability to some extent. The other is in electrically mucky environments, such as around the line timebase of a TV, where a DMM can give horribly false readings. Better DMMs will be more immune to this problem, experienced users will be more aware that it's happening.
