mono versus stereo ampflication

If one has for example 8K to spend on ss amplification for a two channel system, would one in general be better off using a stereo amplifier of perhaps dual mono design or using a set of monoblocks. If the answer is "it depends" what then are the likely trade-offs of each option and on what does it depend?
Do you have any recommendations of specific products for either option for 92db, 8 to 4 ohm speakers?
Thanks for the input. I did find some discussion of this issue on threads that are three years old but nothing recent.
