I've been testing with latest teddy bear's tomato mod and Oleg mod to and for. I like the tomato mod for the following:

1) easier to support Chinese filenames (codepage 936) for Samba
2) more stable support of USB devices
3) better and easier to use/understand interface
4) support of wireless ethernet bridge mode

However, the tomato does not fuse.o and hence ntfs-3g. the current ntfs driver comes with tomato cannot display ntfs partitions properly.

the oleg is good for it's support for twonkymedia and ntfs-3g.
