Does anyone have opinions on textfugu/tofugu and/or skritter

I signed up for TextFugu and did that for a short while until I started RTK. I really like Skritter and use it every day. (I already had a tablet.) It can be addicting.

I guess I'll go back to TextFugu when I'm done with RTK. (It's taking me forever.) TF relies heavily on Anki, which bores the crap out of me.
