The Tax Adviser (an AICPA publication) does a great job every year collecting information on which tax preparation packages are being used by professionals and what they like and dislike about each. This year was no exception — the article is chock-full of useful metrics and covers 13 products. It also lists favorite software by firm size, which I think is a great perspective, and “best for a new practice” ratings.
Check it out — definitely worth a read.
