I would use it, yes. I already have several orchestral elements with other software libraries. I originally wanted SC but have wondered how effective the Wordbuilder would actually be, and if it is the most effectual choir library for the dollar.
This bundle is an incredible value overall, to be sure, given the price. There are, nevertheless, many competing libraries coming out almost every month now, some that are incredible and highly praised for their ever expanding breadth of expressiveness and depth.
One does have to carefully weigh out everything in the balances before spending this amount of money on what is now an increasingly aging fleet of software titles.
