The basics are the same. Fees, ehe quality of the investment lineup, participation, company generosity (ie is there a contribution match). 403(b)'s have bene the news of late because of University plans with higher than normal fees and/or fund line ups that are inadequate.
Best Plan goverance practices for 401k and 403b are to have the plan fees and investment benchmarked regularly to ensure the participants are getting the best deal and that the funds in the investment remain the best for the plan participants.
If you wish to discuss the details of the plan, I could provide more specficic feedback. I can be contacted at 908-841-9764 or via email at email@example.com
