Please answer this: Which version of Vista is better? ?

I just bought a new ASUS laptop, X83VB-X1

http://www.bestbuy.com/site/olspage.jsp?skuId=9050... (sorry.. for some strange reason i couldn't find it on the asus website)

So, the problem is, the laptop came with Home Premium 64bit

I like Vista, but I'm not a fan of Home Premium because i have Ultimate on my desktop. This wouldn't be any problem except that I have Ultimate 32 bit.

I know 64 bit can't run some software, but overall it IS better than 32 bit. But Ultimate is also so much better than Home Premium.

So, should I stay with Home premium 64-bit,

or should I install Ultimate 32-bit?

It would be really helpful if you explained why you prefer whichever OS.

Thanks~
