I choose to have a corded router - DeWalt 625 - only because in my opinion as a DIYer it covered most possible needs, first being a worktop , sink cutout and groves in doors. BUT - I am looking at the DeWalt cordless 1/4" just for the occasional trimming, BUT can't justify the price at the moment.
NOTE - I'm just a DIYer, so occasional use
