unisim one wont be exactly 'new' since they already have a part time accountancy prog which was developed together with kpmg, rsm chio lim, nexus, grant thornton etc, all very established acct firms. my guess is they will very likely just bring the expertise over. since the part time prog is already recognised by acra, will not be difficult for the full time one to do so as well. so maybe u can seriously consider.
then again, you should wait for both unis details to be out.
another advice is, you should go to those unisim threads across different forums to consult the current acct students in unisim. or best speak to them during open houses. i guess they will be more qualified to share experiences and advise you, rather than most of us here who are not in the accountancy fields.
