Compression using spaced pair - seperate channel inserts or post fader?

[karambos2]

If I am recording using a spaced pair micing setup and I want light compression on both mics, would the serious studio engineer use two seperate compressors as inserts on two seperate channels on the mixing desk or are there compressors out there capable of dealing with two inputs and which have two outputs?

Or would you somehow send the post fade stereo signal into one compressor before sending it to whatever recording medium you are using (in my case the hard drive)?

I'm confused about how to apply compression the best.
