I am a business consultant and made many extensive business plans over the last 35 years involving billions of dollars. My answer to your question; I give Business Plan Pro a 9 on a scale of 10. That's about as high of a rating I give software. Of course, I've done many business plans without software or even templates, so I understand their format and structure.
I use the Premier edition and not familiar with the Standard edition because I need to import large amounts of financial data from Excel. The program can be a great time saver, and I feel the learning curve is slight.
I've been using this software for many years and will continue to use it. I do change much of the stock phrases and input info for originality. I feel you would benefit from the software only if you plan to do business plans on a regular basis, otherwise, a simple template out would probably suffice.
I like the SAMPLE business plans provided with BP Pro. It cuts down on reinventing the wheel as to what one should look like for the inexperienced, and gives examples of what's need in the category you are working on. Most importantly, I don't use their stock sentences and phrases for originality because a canned BP is often easy to identify by the experienced, cutting down on the originators credibility.
Palo Alto Software states about BP Pro:
Business Plan Pro is based on a business plan format recognized by banks, lenders, investors, and the Small Business Administration (SBA). Business Plan Pro walks you through the entire planning process and generates a complete, professional and ready to distribute plan with a proven formula for success. I agree with their statement.
I know highly experienced consultants state they donít use Mickey Mouse canned software. Generally, I find they often produce pretty BPís that took enormous amounts of time to produce and made a couple thousand dollars. I was paid $38,000 for one BP I created in BP Pro.

I purchase the upgrade about every 2 years. I've used other software like Business Plan Architect and Virgin's BP Software (I believe no longer available - my favorite)
