I think you should consider a few things with this decision. First, beyond what would look good for CRNA school, how do the individual units compare in terms of work culture, schedule, etc.? You will be spending 1 or 2 years there so you don't want to be with miserable co-workers! If you don't get in the first time, you need to be comfortable staying in that unit because you like it. This was important with me in deciding between ICUs and I made the right choice and love my job and co-workers. Have you shadowed both units? Also, does the hospital have a CRNA program? My SICU has a reputation for having consistent turnover due to CRNA school but my school knows what kind of skill set people from my unit arrive with and that offers them some idea in what I know/don't know. I don't think my interview was as difficult as others from people out of state because they are trying to get a feel for what that candidate was competent with day to day. With me, I think they knew more of what they were getting. I think it would look good for you to branch out from neuro to SICU and make you a more diverse candidate. I work in a level I trauma hospital in the SICU and we see a lot of neuro trauma too (we've had EVD's and bolts lately, most with extensive concurrent ortho injuries) so hopefully you'll get some neuro patients there. I got anesthesia and surgery references from my unit and I think the exposure to the OR team/CRNAs was helpful. Good luck with your decision and best wishes in your pursuit! I can't remove all bias because I really enjoy my unit as a whole and work with my best friends that I've made while here :-) I'm going to Duke in Spring.
