I think some of the arguments are workable for some materials and/or situations. With mdf there's no shrinkage, they hold their shape. with a decent compound mitre saw you can nip off an eigth of an inch until get a good mitred joint. no problem really. You can scribe equally as well or better for them who favour the method. scribing seems to come into its own when using materials which are prone to deviant behaviour, after the joint is made. but this is more to do with the material than the joint. the joint has no say in the behaviour of the material, it exists to compensate. now scribing is probably specified in the contracting, so in that case you do it. you'd also mitre if it was specified in the contrtact. you would instinctively mitre cornicings , dado and picture rails. does anyone do these by scribing? as for joints other than 90 deg. to some extent scribing can be retained but not without a compromise somewhere between the two methods. ie part mitre part scribe. so in all the use of scribing comes down to a fairly narrow bandwidth of applications. whereas mitreing works for all. whatever makes you happy i suppose. i get a lot of pleasure from doing a good mitre.
