For most of my comics, I've been handwriting the text because Krita's text tool is such a hassle. On the plus side, I've relearned how to make my handwriting much better since it's kind of degraded since graduating from school. Also, I feel like it's forced me to be a lot more economical with delivering information since I really don't want to write a lot. Since I do gag comics, it really helps with making sure I keep my jokes quick and snappy.
However, I've been working on another comic lately that's more in the style of a manga, so I've been using the text tool again for that project since my handwriting wouldn't match the theme as much and it's a lot more text-heavy than my usual fare. I've gotten a lot more competent with how the tool operates (@xabelmind covers a good amount of what I ended up learning on my own) but it's still a lot of trouble to work with.
