10 or 25 or nothing?

With my recent decision to place limits on efforts I make in WoW it makes me think about Cataclysm and its changes to 10-man and 25-man raiding. Placing them on the same lockout and having them offer the same rewards (in varying quantities).

When I returned to raiding the last time 10-mans afforded the chance to get a few drops quickly and got me caught up to the minimal level. However it was 25-man that got me the most gear but only because my guild had been raiding for a while at that point and a large amount of gear got defaulted to me.

What do I prefer performance-wise? In 10-mans I feel I have more responsibility. My biggest personal triumphs have occurred in 10-mans. In 25s I do my part but obviously less falls on individual shoulders when 24 others are present.

On the other hand, sometimes I like showing up to raids not having to worry about being totally relied upon.

Success-wise? I still say accomplishing something in 25 is harder than 10. If I got something done in 10-man I would still want to get it done in 25 at some point because I feel 25 is the pinnacle.

But the developers are removing this. If I get something done in 10 I'll be done period. I won't be able to do it on 25 (at least not with some extra tangible reward tied to it) and vice versa.

I like taking extended breaks from raiding. 25s allow for this much easier than 10s.

And now with my new rule of not dedicating myself to any specific raiding goals, should I bother with raiding at all?

I just don't know at this point.
