CAD isn't going to make the average rookie team have an entirely straight frame, properly aligned sprockets and axles, proper chain tensioning, or the general machining precision necessary to have a fully reliable #25 chain drive. While everything may work fine in the computer, it doesn't always translate to the real robot.
#35 chain is plenty reliable and competitive for any team, not just rookies. While #25 has its advantages, I'd suggest rookies spend their resources and times developing other aspects of the drive and whole robot rather than worrying about #25 chain just yet. Spend more of those resources on better wheels, transmissions, electronics, or manipulators (or about anything else). Get done with your drive a little bit quicker with the supplied #35 and let your programmers have more time.
The best thing for a rookie to do is come up with a reliable, fully-functioning, usable drive with enough time for their programmers and other sub-systems to have access to the bot to do what work they need to do. That way they can spend more time programming, testing, de-bugging, and integrating the systems, as well as the all important training of the drivers.
