Label - if getting a particular line on your resume is critical to future success, then maybe a full time MBA would make more sense. Not that doing an EMBA should be seen as a lower qualification - Wharton, as with several other schools, requires that you complete an equal number of credits to receive an MBA whether you reach that degree through the full time or the executive format. In some careers it may be more important that you do that as a full time student. As an entrepreneur, I'm not sure that's quite your situation. My hypothesis is that it's more important to consider what will you gain from the experience as much as the line you get to add to your resume. Executive MBA's appeal to a different crowd - typically you'll find mid to senior level individuals make up the student body. Typically these aren't people who are willing to walk away from a good salary and growing career to go to school for 2 yrs full time.
The connections are strengthened in the setting where the program has a residential requirement. Many EMBA courses run every other week or every few weeks for a few consecutive days at a time. The class stays in the same hotel, studies together, shares evenings together etc. You'll have more conversations, forge stronger links when everyone isn't trying to rush home every night or going back to the office in the middle of periods of study.
The experience is driven as much if not more by your fellow students, what insights they bring and how they challenge you as it is about the professors and the class material. That may not be a different concept than a full time program, it's just that as noted above you're doing that with individuals who have that many more years of work/life experience under their belt.
My point is that the two options (FT or Exec) are different to one another - it's not that one is intrinsically subordinate to the other.
