reiser vs. ext3

I will shortly receive SuSE 9.1. Assuming it allows me to choose between Reiser and Ext3 file systems, which should I choose, and why? (It would be useful to be able to access the Linux system files from Win XP, on the NTFS, if that can be done, and even more so, the reverse--i.e., access NTFS files from Linux.) I am not currently sharing my XP system with any other OS, so this will be a new installation in all respects. All comments and observations gratefully received. --doug
