Sure there is a difference. Several of them, actually. Price, base stocks, additives, marketing, etc.
The real question is probably more accurately put this way:
Is there a reasonable difference, given my personal operational and maintenance plans, to make the cost difference worth while?
Only you can answer that.
You really should be a bit more descriptive when calling out partiuclar products. "Rotella" is a brand line now marketing dino, semi, and full syns. Mobil 1 is a brand line as well, and while it does encompass the TDT, many also consider the Delvac 1 to be more of the specific HDEO (although they are very similar). Amsoil has many good products in their line up.
All these products do a fine job, when you use them with their benefits and limitations in mind. There is no one perfect oil for all conditions. There are "better" choices for given situations.
When you lay out such a general question, we tend to make general answers. But if you want a specific recommendation(s), you need to be much more detailed in your questions. We would want to know about your:
opearational environment
operational severity
maintenance plans
cost threshhold
ease of availability of product
vehicle modifications
etc.
