I think it depends on the application. Those built-in mics sound pretty good. I find when recording ensembles, mics sound better placed high, which is a bit more challenging with built-in mics. You can't see the meters if the unit is place high. If you get a one-point stereo mic, you can position them higher and have the recorder lower (closer) to operate it and see the meters. A couple of one-point stereo mics are:

1. Audio Technica AT 825

2. Rode NT4

Compared to two single mics, one-point stereo mics are easier to use because positioning is faster. With two single mics, placement can take more time, with the possibility of phasing issues if placed incorrectly. However, the two single mics give you more positioning options.

Hope this helps.
