Ultimately I far prefer the æ but I'll survive with the other symbol; I just won't be as happy about it but I'm sure I'll get used to it in time.
I'm not invested in Aeon but read most of the Altcoin threads since its all very addictive. Personally, its' no contest, æ just looks nicer...plus the current logo is lowercase (so you would be loosing the link between the two).
