Hello.
I am planning to upgrade my linux distribution to a new version. Now, I have one 10G reiser part for Linux. I am planning to split this partition into one 5G part for the system and to another 5G part for my home dir.
The question: which filesystem should I choose?
This question was not a question for me, until a few weeks ago my brother told me that ext3 is better than reiser. I made some googling on this, but I only found quite old compares on this issue. My brother told me, that reiser uses more CPU power for doing its job than ext3. He also told me that ext3's journaling is now better. What do you think all about this? In my searches I found that ext3 uses much more space for the directory tree, than reiser. It was an old article too, so I must ask if it changed since then. Anyway: which filesystem is better for everyday use, thus which one should I choose? Thanks.
EDIT: please provide some details why should I choose that FS, because opinions are only opinions. Thanks again.

where i live we get a lot of thunderstorms which cause temporary power outages and thus the computer just up & dies until the power comes back on, (no UPS and don't want one) i found that ext3 recovers quite nicely from this, i have lost data & could not recover the file system in the past using reiserfs from these power outages...

SUSE moved away from reiserfs to ext3 as their default, which made the news late last year. Here is a reasonably comprehensive post that explains the reasons:

If you're planning to dualboot Linux and Windows, keep in mind that accessing an ext2/ext3 partition in Windows is easily done with a simple utility.

Support for reiserfs may prove increasingly difficult to come by in the future, since Hans Reiser has been indicted for murder.

Guilty or not, his defense will take a lot of his time and energy for quite awhile. And if he gets sent up...well, I suppose that he could work on it at least some of the time in prison...

Yes, I am planning to dualboot. You know, reiser can be accessed from windows too. I know, because I do access it. Anyway: which utility are you talking about? The Total Commander filesystem extension? Are there other tools?

Thanks. I think this post is a really good answer to my question.

Ext2/3 for Windows: http://www.fs-driver.org/

Have you looked at Jfs?

Because I multiboot, I normally use Ext2/3 for a more peaceful co-existence.

Right now I'm using Jfs and I have in the past. Is it my imagination or is it much faster than Reiserfs and ext3?

Hi!
JFS? I heard about it, but I don't know if I can use it with Mepis. I think it does not provide it as default. Are there any JFS readers for Win? You know, sometimes I need to access my linux part from win. Anyway: Thanks for your suggestion.

You would need the fs-driver posted earlier if you use Ext2/3. I doubt a tool exists for Jfs.
I create a separate partition(Fat32) just to share files between my windows and linux operating systems.
I'm just suggesting alternatives that will work if you chose not to use Ext2/3 exclusively. There is nothing wrong with Ext and it is the most compatible file system.
I plan to use Jfs more and test it with some hard shutdowns. My experience has shown Ext3 to survive a couple of hard shutdowns if I'm lucky. We have power outages here occasionally.

Well, I think I'll just use Ext3 then. I don't need any complications right now. Anyway: my win part is already a FAT32 part, so it can be accessed any time from Linux. A win to linux access is more needed right now.

I have ext3 partitions that have been through more than 6 power outage unexpected losses of power and have never lost data to it yet knock on wood.
