5 years for an undergraduate education seems quite long for most people, not to mention the cost of paying an extre years worth of tuition. If you’re leaning more towards engineering, you should go directly to an engineering school (and maybe just GA Tech if you’re in-state to save on costs) and you can always do pre-med at the same time by taking the prerequisites and doing the pre-med ECs. If you’re leaning more towards pre-med, I would try to get into a combined BS/MD program directly from high school since these can often be completed in 6-7 years (rather than the normal 8 years if you apply after 4 years of undergrad) and offer guarantees for med school admission as long as the minimum GPA/MCAT is met (otherwise med school admissions is very competitive these days and involves a lot less certainty of admission). Unfortunately Emory does not offer such a program w/ its med school.
