feeding most annuals, balanced or ?

I've been gardening a long time, but always ponder which fertilizer to use for annuals since I grow mostly perennials and mix in annuals. I've usually used the 15-30-15, but also have tried the 15-50-15 and the balanced 20-20-20 by Schultz. This year one of the greenhouses recommended the typical 15-30-15, but another one was insistent on using the balanced one. Has anyone studied which formula gives you the best consistent flowering for the entire season?

Thanks ahead of time!
