It really depends a lot on NA/turbo, driving habits, and driving conditions. I only use very high quality (Redline) full-synth in the STi because 1) it is turbo 2) I go WOT often 3) I run higher than stock boost levels.
Someone may also use full synth/blend to increase their OCI.
Just as a side note, I have had bad experience (noticeable shearing before 3k miles) with M1 full synth in my '04 WRX. I would imagine; however, that it would be an excellent oil in an NA Honda. I think they only call for a 20 weight anyway.
